A new thiospinel CuCrZrS 4 has been successfully synthesized by a solid-state chemical reaction. This CuCrZrS 4 exhibits ferromagnetic properties below the Curie temperature at T c = 60 ± 2 K. The appearance of irreversibility between field-cooled (F.C.) and zero-field cooled (Z.F.C.) magnetization is prominent below around 5 K in less than 150 Oe. The ac susceptibility χ AC shows a rapid decrease below ≈10 K. This low-magnetic field behaviour indicates the existence of a reentrant spin glass phase below ≈10 K. The d.c. magnetic susceptibility above 100 K shows Curie-Weiss behaviour with the effective magnetic moment of 3.61 µ B , which is a little less than the spin only value of 3.87 µ B for Cr 3+ ion. The asymptotic Curie temperature θ p is approximately 65 K which is a little higher than T c. The valence state is confirmed to be Cu + Cr 3+ Zr 4+ S 2-4 on the basis of magnetic properties. Electrical resistivity ρ shows a semiconducting temperature dependence over the temperature range 4.2 to 280 K with an activation energy of 6.84×10-3 eV in the higher temperature range 50 to 283 K.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
