%X 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 Kwith a relatively large saturated magnetisation of 4.5 lB. TheM=Niproduct,CaMn1.2Ni0.8ReO6, is a remarkable exampleof a ferromagnetic oxide with four distinct spin sublattices all collinearly ordered below TC = 152 K.
