  text: UTe2 exhibits the remarkable phenomenon of re-entrant superconductivity, whereby
    the zero-resistance state reappears above 40 tesla after being suppressed with
    a field of around 10 tesla. 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 magnetization measurements
    show no sign of strong fluctuations. 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.
    The three superconducting phases of UTe2, including the high-field re-entrant
    phase, surround this region of enhanced susceptibility in the field-angle phase
    diagram. The strongest transverse susceptibility is found near the critical end
    point of the high-field metamagnetic transition, suggesting that quantum critical
    fluctuations of a field-induced magnetic order parameter may be responsible for
    the large transverse susceptibility, and may provide a pairing mechanism for field-induced
    superconductivity in UTe2.

  text: 'Magnetotropic susceptibility is the thermodynamic coefficient that maps the
    curvature of free energy with respect to an applied magnetic field orientation,
    providing a means to quantify the magnetic anisotropy of a crystal. 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.'

  text: "We compute the rotational anisotropy of the free energy of \U0001D6FC−RuCl3
    in an external magnetic field. This quantity, known as the magnetotropic susceptibility,
    \U0001D458, relates to the second derivative of the free energy with respect to
    the angle of rotation. We have used approximation-free, auxiliary-field quantum
    Monte Carlo simulations for a realistic model of \U0001D6FC−RuCl3 and optimized
    the path integral to alleviate the negative sign problem. This allows us to reach
    temperatures down to 30K—an energy scale below the dominant Kitaev coupling. We
    demonstrate that the magnetotropic spin susceptibility in this model of \U0001D6FC−RuCl3
    displays scaling behavior \U0001D458=\U0001D447⁢\U0001D453⁡(\U0001D435/\U0001D447)
    at high temperatures. Once the uniform susceptibility departs from the Curie law
    (i.e., at the energy scale of the exchange interactions), it appears to transition
    to an emergent scalinglike behavior, characterized by a different function \U0001D453
    at lower temperatures, stemming from the locality of torque fluctuations. We observe
    a remarkable numerical match between experiment and simulations and we also find
    qualitative agreement with the pure Kitaev model. In comparison, for the XXZ Heisenberg
    Hamiltonian, the scaling \U0001D458=\U0001D447⁢\U0001D453⁡(\U0001D435/\U0001D447)
    breaks down at a temperature scale where the uniform spin susceptibility deviates
    from the Curie law and never reemerges at low temperatures."

  text: Magnetic frustration allows to access novel and intriguing properties of magnetic
    systems and has been explored mainly in planar triangular-like arrays of magnetic
    ions. In this work, we describe the phosphide Ce6Ni6P17, where the Ce+3 ions accommodate
    in a body-centered cubic lattice of Ce6 regular octahedra. From measurements of
    magnetization, specific heat, and resistivity, we determine a rich phase diagram
    as a function of temperature and magnetic field in which different magnetic phases
    are found. Besides clear evidence of magnetic frustration is obtained from entropy
    analysis. At zero field, a second-order antiferromagnetic transition occurs at
    TN1≈1 K followed by a first-order transition at TN2≈0.45 K. With magnetic field
    new magnetic phases appear, including a weakly first-order transition which ends
    in a classical critical point and a third magnetic phase. We also study the exact
    solution of the spin-1/2 Heisenberg model in an octahedron which allows us a qualitative
    understanding of the phase diagram and compare with the experimental results.

  text: The magnetotropic susceptibility is the thermodynamic coefficient associated
    with the rotational anisotropy of the free energy in an external magnetic field
    and is closely related to the magnetic susceptibility. It emerges naturally in
    frequency-shift measurements of oscillating mechanical cantilevers, which are
    becoming an increasingly important tool in the quantitative study of the thermodynamics
    of modern condensed-matter systems. Here we discuss the basic properties of the
    magnetotropic susceptibility as they relate to the experimental aspects of frequency-shift
    measurements, as well as to the interpretation of those experiments in terms of
    the intrinsic properties of the system under study.

  text: Electrically tunable lenses (ETLs) are those with the ability to alter their
    optical power in response to an electric signal. 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

  text: Magnetic anisotropy in strontium iridate (Sr2IrO4) is essential because of
    its strong spin–orbit coupling and crystal field effect. 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.

  text: Multistable systems are characterized by exhibiting domain coexistence, where
    each domain accounts for the different equilibrium states. In case these systems
    are described by vectorial fields, domains can be connected through topological
    defects. Vortices are one of the most frequent and studied topological defect
    points. Optical vortices are equally relevant for their fundamental features as
    beams with topological features and their applications in image processing, telecommunications,
    optical tweezers, and quantum information. A natural source of optical vortices
    is the interaction of light beams with matter vortices in liquid crystal cells.
    The rhythms that govern the emergence of matter vortices due to fluctuations are
    not established. Here, we investigate the nucleation mechanisms of the matter
    vortices in liquid crystal cells and establish statistical laws that govern them.
    Based on a stochastic amplitude equation, the law for the number of nucleated
    vortices as a function of anisotropy, voltage, and noise level intensity is set.
    Experimental observations in a nematic liquid crystal cell with homeotropic anchoring
    and a negative anisotropic dielectric constant under the influence of a transversal
    electric field show a qualitative agreement with the theoretical findings.

  text: A facile approach for developing an interfacial solar evaporator by heat localization
    of solar-thermal energy conversion at water-air liquid composed by in-situ polymerization
    of Fe2O3 nanoparticles (Fe2O3@PPy) deposited over a facial sponge is proposed.
    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.

  text: In RuCl3, inelastic neutron scattering and Raman spectroscopy reveal a continuum
    of non-spin-wave excitations that persists to high temperature, suggesting the
    presence of a spin liquid state on a honeycomb lattice. In the context of the
    Kitaev model, finite magnetic fields introduce interactions between the elementary
    excitations, and thus the effects of high magnetic fields that are comparable
    to the spin-exchange energy scale must be explored. Here, we report measurements
    of the magnetotropic coefficient—the thermodynamic coefficient associated with
    magnetic anisotropy—over a wide range of magnetic fields and temperatures. We
    find that magnetic field and temperature compete to determine the magnetic response
    in a way that is independent of the large intrinsic exchange-interaction energy.
    This emergent scale-invariant magnetic anisotropy provides evidence for a high
    degree of exchange frustration that favours the formation of a spin liquid state
    in RuCl3.

  text: Several Ising-type magnetic van der Waals (vdW) materials exhibit stable magnetic
    ground states. Despite these clear experimental demonstrations, a complete theoretical
    and microscopic understanding of their magnetic anisotropy is still lacking. In
    particular, the validity limit of identifying their one-dimensional (1-D) Ising
    nature has remained uninvestigated in a quantitative way. 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. Our approach can be applied to
    the detailed quantitative study of magnetism in vdW materials.

    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. The F45G55 nanohybrid was found to be the best for hyperthermia applications
    in low dosage with the highest specific absorption rate (SAR) and mean squared
    error values.

  text: An understanding of the missing antinodal electronic excitations in the pseudogap
    state is essential for uncovering the physics of the underdoped cuprate high-temperature
    superconductors1,2,3,4,5,6. The majority of high-temperature experiments performed
    thus far, however, have been unable to discern whether the antinodal states are
    rendered unobservable due to their damping or whether they vanish due to their
    gapping7,8,9,10,11,12,13,14,15,16,17,18. Here, we distinguish between these two
    scenarios by using quantum oscillations to examine whether the small Fermi surface
    pocket, found to occupy only 2% of the Brillouin zone in the underdoped cuprates19,20,21,22,23,24,
    exists in isolation against a majority of completely gapped density of states
    spanning the antinodes, or whether it is thermodynamically coupled to a background
    of ungapped antinodal states. We find that quantum oscillations associated with
    the small Fermi surface pocket exhibit a signature sawtooth waveform characteristic
    of an isolated two-dimensional Fermi surface pocket25,26,27,28,29,30,31,32. This
    finding reveals that the antinodal states are destroyed by a hard gap that extends
    over the majority of the Brillouin zone, placing strong constraints on a drastic
    underlying origin of quasiparticle disappearance over almost the entire Brillouin
    zone in the pseudogap regime7,8,9,10,11,12,13,14,15,16,17,18.
