Ferri- and ferro-magnetism in CaMnMReO 6 double double perovskites of late transition metals M = Co and Ni. Chemical Communications, 2019, 55 (18), pp.2605-2608.10.1039/c8cc09612khttps://hdl.handle.net/20.500.14352/114053Two 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.engAttribution-NonCommercial 4.0 Internationalhttp://creativecommons.org/licenses/by-nc/4.0/Ferri- and ferro-magnetism in CaMnMReO6 double double perovskites of late transition metals M = Co and Nijournal articlehttps://doi-org.bucm.idm.oclc.org/10.1039/C8CC09612Kopen access546Química inorgánica (Química)2303 Química Inorgánica
