 note = {application/pdf, A new thiospinel CuCrZrS4 has been successfully synthesized by a solid-state chemical reaction. This CuCrZrS4 exhibits ferromagnetic properties below the Curie temperature at Tc=60±2 K. The appearance of irreversible effect between field-cooled and zero-field-cooled magnetization is prominent below around 5 K in a magnetic field of less than 150 Oe. The ac susceptibility χAC shows a rapid decrease below about 10 K. This low magnetic-field behaviour indicates the existence of a re-entrant spin-glass phase below about 10 K. The dc magnetic susceptibility above 100 K shows Curie-Weiss behaviour with an effective magnetic moment of 3.61 μB, which is a little less than the spin-only value of 3.87 μB for the Cr3+ ion. The asymptotic Curie temperature &thetas;p is approximately 65 K, which is a little higher than Tc. The valence state is confirmed to be Cu+Cr3+Zr4+S42- on the basis of magnetic properties. The electrical resistivity ρ shows a semiconducting temperature dependence over the temperature range from 4.2 to 280 K with an activation energy of 6.84×10-3 eV in the higher temperature range from 50 to 283 K},
