One potential pairing mechanism, invoked in the related re-entrant superconductors UCoGe and URhGe, involves transverse fluctuations of a ferromagnetic order parameter. However, the requisite ferromagnetic order—present in both UCoGe and URhGe—is absent in UTe2, and neutron scattering shows instead that the magnetic susceptibility is peaked at an antiferromagnetic wavevector. Here, we measure the magnetotropic susceptibility of UTe2 across two field-angle planes. This quantity is sensitive to the magnetic susceptibility in a direction transverse to the applied magnetic field—a quantity that is not accessed in conventional magnetization measurements. We observe a very large decrease in the magnetotropic susceptibility over a broad range of field orientations, indicating a large increase in the transverse magnetic susceptibility. Because our technique probes the magnetic susceptibility in the long wavelength (q = 0) limit, this suggests that the strong transverse susceptibility arises from ferromagnetic spin fluctuations. These ferromagnetic fluctuations are likely important for understanding the pairing mechanism in UTe2, as all three superconducting phases of UTe2 surround this region of enhanced susceptibility in the field-angle phase diagram."}],"corr_author":"1","PlanS_conform":"1","publication_identifier":{"eissn":["2041-1723"]},"oa_version":"Published Version","has_accepted_license":"1","date_updated":"2026-05-11T06:36:00Z","publisher":"Springer Nature","year":"2026","volume":17,"DOAJ_listed":"1","publication_status":"published","scopus_import":"1","OA_place":"publisher","author":[{"first_name":"Valeska","id":"467ed36b-dc96-11ea-b7c8-b043a380b282","last_name":"Zambra","full_name":"Zambra, Valeska","orcid":"0000-0002-8806-5719"},{"last_name":"Nathwani","full_name":"Nathwani, Amit","first_name":"Amit","id":"1a362536-4d02-11f1-8543-8351136efc50"},{"last_name":"Nauman","full_name":"Nauman, Muhammad","orcid":"0000-0002-2111-4846","first_name":"Muhammad","id":"32c21954-2022-11eb-9d5f-af9f93c24e71"},{"first_name":"Sylvia K.","last_name":"Lewin","full_name":"Lewin, Sylvia K."},{"first_name":"Corey E.","full_name":"Frank, Corey E.","last_name":"Frank"},{"last_name":"Butch","full_name":"Butch, Nicholas P.","first_name":"Nicholas P."},{"full_name":"Shekhter, Arkady","last_name":"Shekhter","first_name":"Arkady"},{"full_name":"Ramshaw, B.

In this context, non-linear magnetic torque behavior has been reported in FePS3, motivating the investigation of similar non-linear characteristics in its magnetotropic susceptibility. In this work, we derive the non-linear magnetotropic susceptibility expressions for FePS3 in both ac*-and bc*-planes using complementary approaches: by taking the first derivative of torque and through the formal calculation of the magnetotropic susceptibility. Higher-order terms in the magnetization are included, and the final equations are obtained by applying symmetry constraints imposed by the C2h point group of the material. We analyze the behavior of the resulting non-linear expressions and identify the contributions of each parameter. Our theoretical results show good agreement with preliminary, unpublished experimental data, offering meaningful guidance for ongoing and future experimental work.","lang":"eng"}],"department":[{"_id":"KiMo"}],"date_published":"2025-10-06T00:00:00Z","pmid":1,"acknowledgement":"We thank Kimberly A.

This feature allows such systems to not only image the areas of interest but also obtain spatial depth perception (depth of field, DOF). The aim of the present study was to develop an ETL-based imaging system for quantitative surface analysis. Firstly, the system was calibrated to achieve high depth resolution, warranting the accurate measurement of the depth and to account for and correct any influences from external factors on the ETL. This was completed using the Tenengrad operator which effectively identified the plane of best focus as demonstrated by the linear relationship between the control current applied to the ETL and the height at which the optical system focuses. The system was then employed to measure amplitude, spatial, hybrid, and volume surface texture parameters of a model material (pharmaceutical dosage form) which were validated against the parameters obtained using a previously validated surface texture analysis technique, optical profilometry. There were no statistically significant differences between the surface texture parameters measured by the techniques, highlighting the potential application of ETL-based imaging systems as an easily adaptable and low-cost alternative surface texture analysis technique to conventional microscopy techniques"}],"department":[{"_id":"KiMo"}],"date_published":"2022-01-01T00:00:00Z","language":[{"iso":"eng"}],"acknowledgement":"The authors acknowledge the financial assistance provided by the University of Huddersfield.","fulldoi":"https://doi.org/10.3390/mi13010017","status":"public","month":"01","citation":{"chicago":"Nirwan, Jorabar Singh, Shan Lou, Saqib Hussain, Muhammad Nauman, Tariq Hussain, Barbara R.

In this paper, we present a detailed mapping of the out-of-plane (OOP) magnetic anisotropy in Sr2IrO4 for different sample orientations using torque magnetometry measurements in the low-magnetic-field region before the isospins are completely ordered. Dominant in-plane anisotropy was identified at low fields, confirming the b axis as an easy magnetization axis. Based on the fitting analysis of the strong uniaxial magnetic anisotropy, we observed that the main anisotropic effect arises from a spin–orbit-coupled magnetic exchange interaction affecting the OOP interaction. The effect of interlayer exchange interaction results in additional anisotropic terms owing to the tilting of the isospins. The results are relevant for understanding OOP magnetic anisotropy and provide a new way to analyze the effects of spin–orbit-coupling and interlayer magnetic exchange interactions. This study provides insight into the understanding of bulk magnetic, magnetotransport, and spintronic behavior on Sr2IrO4 for future studies."}],"date_published":"2022-01-20T00:00:00Z","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)","image":"/images/cc_by.png"},"external_id":{"isi":["000775191800001"],"pmid":["34986467"]},"file":[{"content_type":"application/pdf","file_id":"10741","date_updated":"2022-02-07T10:35:28Z","success":1,"access_level":"open_access","checksum":"b6c705c7f03dcb1dbcb06b1b4d4938d6","date_created":"2022-02-07T10:35:28Z","relation":"main_file","file_name":"2022_JPhysCondensMatter_Nauman.pdf","file_size":1742414,"creator":"cchlebak"}],"year":"2022","volume":34,"date_updated":"2026-08-12T14:03:01Z","has_accepted_license":"1","publisher":"IOP Publishing","scopus_import":"1","author":[{"first_name":"Muhammad","id":"32c21954-2022-11eb-9d5f-af9f93c24e71","full_name":"Nauman, Muhammad","last_name":"Nauman","orcid":"0000-0002-2111-4846"},{"first_name":"Tayyaba","full_name":"Hussain, Tayyaba","last_name":"Hussain"},{"first_name":"Joonyoung","full_name":"Choi, Joonyoung","last_name":"Choi"},{"full_name":"Lee, Nara","last_name":"Lee","first_name":"Nara"},{"first_name":"Young Jai","full_name":"Choi, Young Jai","last_name":"Choi"},{"first_name":"Woun","full_name":"Kang, Woun","last_name":"Kang"},{"first_name":"Younjung","full_name":"Jo, Younjung","last_name":"Jo"}],"publication_status":"published","publication_identifier":{"eissn":["1361-648X"]},"oa_version":"Published Version","quality_controlled":"1","article_type":"original","day":"20","oa":1,"date_created":"2022-02-06T23:01:31Z","file_date_updated":"2022-02-07T10:35:28Z","publication":"Journal of Physics: Condensed Matter","_id":"10735","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","title":"Low-field magnetic anisotropy of Sr2IrO4","isi":1,"article_processing_charge":"No","ddc":["530"],"article_number":"135802","intvolume":"        34","doi":"10.1088/1361-648X/ac484d","issue":"13","type":"journal_article","citation":{"ista":"Nauman M, Hussain T, Choi J, Lee N, Choi YJ, Kang W, Jo Y. 2022.

The demonstrated system consists of a floating solar receiver having a vertically cross-linked microchannel for wicking up saline water. The in situ polymerized Fe2O3@PPy interfacial layer promotes diffuse reflection and its rough black surface allows Omni-directional solar absorption (94%) and facilitates efficient thermal localization at the water/air interface and offers a defect-rich surface to promote heat localization (41.9 °C) and excellent thermal management due to cellulosic content. The self-floating composite foam reveals continuous vapors generation at a rate of 1.52 kg m−2 h−1 under one 1 kW m−2 and profound evaporating efficiency (95%) without heat losses that dissipates in its surroundings. Indeed, long-term evaporation experiments reveal the negligible disparity in continuous evaporation rate (33.84 kg m−2/8.3 h) receiving two sun solar intensity, and ensures the stability of the device under intense seawater conditions synchronized with excellent salt rejection potential. More importantly, Raman spectroscopy investigation validates the orange dye rejection via Fe2O3@PPy solar evaporator. The combined advantages of high efficiency, self-floating capability, multimedia rejection, low cost, and this configuration are promising for producing large-scale solar steam generating systems appropriate for commercial clean water yield due to their scalable fabrication."}],"department":[{"_id":"KiMo"}],"external_id":{"isi":["000736602200001"]},"tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)","image":"/images/cc_by.png"},"file":[{"creator":"alisjak","file_size":4569639,"file_name":"2021_Crystals_Yuzheng.pdf","access_level":"open_access","checksum":"668e9d777608ce0a3bc2e305133bd06b","date_created":"2022-01-03T09:46:53Z","relation":"main_file","file_id":"10591","date_updated":"2022-01-03T09:46:53Z","success":1,"content_type":"application/pdf"}]},{"department":[{"_id":"KiMo"}],"abstract":[{"lang":"eng","text":"Several Ising-type magnetic van der Waals (vdW) materials exhibit stable magnetic ground states.

Here we performed the complete mapping of magnetic anisotropy for a prototypical Ising vdW magnet FePS3 for the first time. Combining torque magnetometry measurements with their magnetostatic model analysis and the relativistic density functional total energy calculations, we successfully constructed the three-dimensional (3-D) mappings of the magnetic anisotropy in terms of magnetic torque and energy. The results not only quantitatively confirm that the easy axis is perpendicular to the ab plane, but also reveal the anisotropies within the ab, ac, and bc planes.

We adopted the wet chemical procedure, using various contents of Fe3O4 (magnetite) from 0–100% for making two-dimensional graphene–Fe3O4 nanohybrids. The homogeneous dispersal of Fe3O4 nanoparticles decorated on the graphene surface combined with their biocompatibility and high thermal conductivity make them an excellent material for magnetic hyperthermia. The morphological and magnetic properties of the nanohybrids were studied using scanning electron microscopy (SEM) and a vibrating sample magnetometer (VSM), respectively. The smart magnetic platforms were exposed to an alternating current (AC) magnetic field of 633 kHz and of strength 9.1 mT for studying their hyperthermic performance. The localized antitumor effects were investigated with artificial neural network modeling. A neural net time-series model was developed for the assessment of the best nanohybrid composition to serve the purpose with an accuracy close to 100%. Six Nonlinear Autoregressive with External Input (NARX) models were obtained, one for each of the components. The assessment of the accuracy of the predicted results has been done on the basis of Mean Squared Error (MSE). The highest Mean Squared Error value was obtained for the nanohybrid containing 45% magnetite and 55% graphene (F45G55) in the training phase i.e., 0.44703, which is where the model achieved optimal results after 71 epochs.

X-ray diffraction analysis revealed that the perovskite crystal structure possesses characteristic sharp and crystalline peaks for all synthesized ternary electrocatalysts. The average particle size calculated using Debye–Scherrer equation was in the order of La0.5Ca0.5NiO3 (LCNO) > La0.5Ca0.5CoO3 (LCCO)> La0.5Ca0.5MnO3 (LCMO). The elemental composition of as prepared sample, LCCO was investigated via x-ray fluorescence spectroscopy. The qualitative and quantitative analysis revealed the presence of La, Ca and Co in parent crystal structure with percentage compositions of 9.0, 3.12 and 87.82% respectively. The particle size distribution was homogenous, as determined by scanning electron and transmission electron microscopes. The electrocatalytic activity of the synthesized ternary electrocatalysts was studied electrochemically by cyclic voltammetry. The calculated diffusion coefficient values showed that electrode surface of LCNO and LCCO have limited efficiency for diffusion related phenomenon. The heterogeneous rate constants inferred better electrode kinetics of LCCO and LCNO which exhibited good electrocatalytic behavior; sharp anodic peaks were observed in the potential range of +0.3 to 0.6 V and +0.6 to 0.8 V, respectively. Methanol electro-oxidation was found minimal in case of LCMO sample. We have observed that Co substitution at B-site of perovskite electrode materials attains better electrochemical properties, thus in relation with reported literature."}],"date_published":"2020-01-15T00:00:00Z","extern":"1","volume":6,"year":"2020","publisher":"IOP Publishing","date_updated":"2021-02-04T07:21:35Z","author":[{"last_name":"Hussain","full_name":"Hussain, Tayyaba","first_name":"Tayyaba"},{"first_name":"Muhammad","id":"32c21954-2022-11eb-9d5f-af9f93c24e71","last_name":"Nauman","full_name":"Nauman, Muhammad","orcid":"0000-0002-2111-4846"},{"full_name":"Sabahat, Sana","last_name":"Sabahat","first_name":"Sana"},{"first_name":"Saira","full_name":"Arif, Saira","last_name":"Arif"}],"publication_status":"published","publication_identifier":{"issn":["2053-1591"]},"oa_version":"None","day":"15","article_type":"original","quality_controlled":"1","publication":"Materials Research Express","_id":"9069","date_created":"2021-02-02T15:53:57Z","keyword":["Electronic","Optical and Magnetic Materials","Surfaces","Coatings and Films","Polymers and Plastics","Metals and Alloys","Biomaterials"],"title":"Synthesis of ternary electrocatalysts for exploration of methanol electro-oxidation in alkaline media","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","article_processing_charge":"No","article_number":"1250g6","intvolume":"         6","doi":"10.1088/2053-1591/ab6886","issue":"12","type":"journal_article","citation":{"mla":"Hussain, Tayyaba, et al. “Synthesis of Ternary Electrocatalysts for Exploration of Methanol Electro-Oxidation in Alkaline Media.” <i>Materials Research Express</i>, vol. 6, no. 12, 1250g6, IOP Publishing, 2020, doi:<a href=\"https://doi.org/10.1088/2053-1591/ab6886\">10.1088/2053-1591/ab6886</a>.","ieee":"T.

In this study, antiferromagnet-based spintronic functionality is demonstrated by combining unique characteristics of the isospin state in Sr2IrO4. Based on magnetic and transport measurements, large and highly anisotropic magnetoresistance (AMR) is obtained by manipulating the antiferromagnetic isospin domains. First-principles calculations suggest that electrons whose isospin directions are strongly coupled to in-plane net magnetic moment encounter the isospin mismatch when moving across antiferromagnetic domain boundaries, which generates a high resistance state. By rotating a magnetic field that aligns in-plane net moments and removes domain boundaries, the macroscopically-ordered isospins govern dynamic transport through the system, which leads to the extremely angle-sensitive AMR. As with this work that establishes a link between isospins and magnetotransport in strongly spin-orbit-coupled AFM Sr2IrO4, the peculiar AMR effect provides a beneficial foundation for fundamental and applied research on AFM spintronics.","lang":"eng"}],"extern":"1","date_published":"2018-10-29T00:00:00Z"},{"title":"Pressure-induced metal–insulator transitions in chalcogenide NiS2-Se","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","quality_controlled":"1","article_type":"original","language":[{"iso":"eng"}],"day":"01","fulldoi":"https://doi.org/10.1016/j.physb.2017.11.032","_id":"9068","abstract":[{"lang":"eng","text":"We report the temperature-dependent resistivity ρ(T) of chalcogenide NiS2-xSex (x = 0.1) using hydrostatic pressure as a control parameter in the temperature range of 4–300 K.

The magnetic-field-dependent torque τ(H) showed a prominent transition from the canted antiferromagnetic state to the weak ferromagnetic (WFM) state. A comprehensive analysis was conducted to examine the isotropic and anisotropic regimes and probe the easy magnetization axis along the a b plane. The angle-dependent torque τ(θ) revealed a deviation from the sinusoidal behavior, and small differences in hysteresis were observed around 0° and 90° in the low-magnetic-field regime. This indicates that the orientation of the easy axis of the FM component is along the b axis, where the antiferromagnetic to WFM spin-flop transition occurs.
