本文报道了两种新的双双钙钛矿型化合物CaMnMReO_6(M = Co,Ni)。M = Co材料具有细化的成分CaMn 0.7Co 1.3ReO 6,并且在TC = 188 K以下具有相对大的饱和磁化强度4.5 μB的铁磁有序。M = Ni的产物CaMn1.2Ni0.8ReO6是一个显著的例子,它具有四个不同的自旋亚晶格,在TC = 152 K以下共线排列。
Two new double double perovskites of ideal compositions CaMnMReO6 (M = Co, Ni) are reported. The M = Co material has refined composition CaMn0.7Co1.3ReO6 and orders ferrimagnetically below TC = 188 K with a relatively large saturated magnetisation of 4.5 μB. The M = Ni product, CaMn1.2Ni0.8ReO6, is a remarkable example of a ferromagnetic oxide with four distinct spin sublattices all collinearly ordered below TC = 152 K.
