Magnetic properties of the quadruple perovskite solid solutions Ca1–xYxCu3Fe4O12 and Y1–yCeyCu3Fe4O12 are investigated. Ca1–xYxCu3Fe4O12 shows continuous increase in the ferromagnetic transition temperature as x increases. Y1–yCeyCu3Fe4O12 exhibits a ferromagnetic-antiferromagnetic transition in the vicinity of y = 0.5. These observations demonstrate the electron doping effect on magnetic properties of charge-disproportionated ACu3Fe4O12 phases.
