摘要：
Solid solutions between ferrimagnet Cu0.5Fe0.5Cr2S4 (TC = 347 K) and antiferromagnet Cu0.5Ga0.5Cr2S4 (TN = 31 K) have been synthesized, and their magnetic properties studied. Both compounds belong to the A0.5+A0.53+Cr2X4 group with the 1 : 1 order of A+ and A3+ ions in the tetrahedral spinel sites. Measurements on a SQUID magnetometer over wide ranges of fields (0.05–40 kOe) and temperatures (5–300 K) provided a deeper insight into the nature of magnetism and cation distribution in the studied samples.
