Processing-dependent CMR properties of Ca(Cu,Mn) 7O 12 manganites

A strong dependence of physical properties on preparation conditions was found for the perovskite-like CaMn 3 – xCu xMn 4O 12 solid solution demonstrating a record negative magnetoresistance of –65% at 35 K in a field of 5 T, for x = 1.0.
