Abstract

We have carried out dc magnetic susceptibility, magnetization and specific-heat measurements on thiospinel CuCrZrS₄. Below T_C^*=51\phantom\rule0.3em0exK, dc magnetic susceptibility and magnetization data show ferromagnetic behavior with a small spontaneous magnetization 0.36\ensuremathμ_B∕f.u. In dc magnetic susceptibility, large and weak irreversibilities are observed below T_f=6\phantom\rule0.3em0exK and in the range T_f<T<T_C^*, respectively. We found that there is no anomaly as a peak or step in the specific heat at T_C^*.
