--- res: bibo_abstract: - 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 insulating behavior of ρ(T) survives at low temperatures in the pressure regime below 7.5 kbar, whereas a clear insulator-to-metallic transition is observed above 7.5 kbar. Two types of magnetic transitions, from the paramagnetic (PM) to the antiferromagnetic (AFM) state and from the AFM state to the weak ferromagnetic (WF) state, were evaluated and confirmed by magnetization measurement. According to the temperature–pressure phase diagram, the WF phase survives up to 7.5 kbar, and the transition temperature of the WF transition decreases as the pressure increases, whereas the metal–insulator transition temperature increases up to 9.4 kbar. We analyzed the metallic behavior and proposed Fermi-liquid behavior of NiS1.9Se0.1.@eng bibo_authorlist: - foaf_Person: foaf_givenName: Tayyaba foaf_name: Hussain, Tayyaba foaf_surname: Hussain - foaf_Person: foaf_givenName: Myeong-jun foaf_name: Oh, Myeong-jun foaf_surname: Oh - foaf_Person: foaf_givenName: Muhammad foaf_name: Nauman, Muhammad foaf_surname: Nauman foaf_workInfoHomepage: http://www.librecat.org/personId=32c21954-2022-11eb-9d5f-af9f93c24e71 orcid: 0000-0002-2111-4846 - foaf_Person: foaf_givenName: Younjung foaf_name: Jo, Younjung foaf_surname: Jo - foaf_Person: foaf_givenName: Garam foaf_name: Han, Garam foaf_surname: Han - foaf_Person: foaf_givenName: Changyoung foaf_name: Kim, Changyoung foaf_surname: Kim - foaf_Person: foaf_givenName: Woun foaf_name: Kang, Woun foaf_surname: Kang bibo_doi: 10.1016/j.physb.2017.11.032 bibo_volume: 536 dct_date: 2018^xs_gYear dct_isPartOf: - http://id.crossref.org/issn/0921-4526 dct_language: eng dct_publisher: Elsevier@ dct_title: Pressure-induced metal–insulator transitions in chalcogenide NiS2-Se@ ...
