摘要
The spinel-type compounds MYb2S4 (M = Mg, Mn) have been prepared and magnetic susceptibility measurements have been carried out. Two types of sample for MnYb2S4 were obtained. The stable phase has a normal-spinel structure and the newly found metastable phase has a modified spinel structure which is not the inverse spinel. Susceptibility data show clearly the difference between both samples of MnYb2S4, which reflects the difference of the crystal field on Yb3+ ions. Moreover, the magnitude of the FC susceptibility data for each type of MnYb2S4 is slightly larger than that of ZFC below about 50 K, while such difference is not observed for MgYb2S4.
