Third series. B, Condensed matter and materials physics}, month = {Dec}, note = {application/pdf, We have carried out dc magnetic susceptibility, magnetization and specific-heat measurements on thiospinel CuCrZrS4. Below TC*=51 K, dc magnetic susceptibility and magnetization data show ferromagnetic behavior with a small spontaneous magnetization 0.36μB/f.u. In dc magnetic susceptibility, large and weak irreversibilities are observed below Tf=6 K and in the range Tf
