摘要：

X-ray diffraction studies performed here indicated solid-solution formation between ZnCr2Se4 and CuCr2Se4, and all the compounds could be indexed on the basis of cubic spinel lattice. The compositions between 0 ≤x ≤ 0.8 showed semi-conducting behaviour, while CuCr2Se4 (x=1.0) exhibited metallic conductivity. Seebeck measurements showd P-type behaviour for 0 ≤x ≤ 1. Magnetic hysteresis indicated a ferromagnetic nature for all the compounds except ZnCr2Se4 (x=0). The shapes of χ/χi plotted against T exhibited single domain behaviour, and Curie temperatures showed an increase with increasing copper concentration. © 1990 Chapman and Hall Ltd.
