摘要:

Crystals of EuSm2S4and SrSm2S4having the cubic Th3P4structure are insulators, with a random distribution of Sr2+and Sm3+over equivalent sites. EuSm2S4is a ferromagnet withTc=2.7 K. SrSm2S4does not order magnetically above 1.4 K. A sharp upturn in its specific heat below 4 K is attributed to splitting of the &Ggr;8quartet by a small non‐cubic crystal field.
