Аннотация: The electron spin resonance (ESR) in CuCrS(2) disulphides is found to be strongly dependent on a synthesis method used. At a temperature of 300 K, a polycrystalline CuCrS(2) sample is paramagnetic with a g-value of 1.95 at 40 K, it undergoes the magnetic transition. In the temperature range 4.2-290 K, a single-crystal sample prepared by a chemical vapor transport method exhibits the ESR features typical of a ferromagnet. It is shown that these features are related to the presence of a small amount of the single-crystal CuCr(2)S(4) impurity in the CuCrS(2) single crystal. (C) 2010 American Institute of Physics.
