dc.description.abstractA site doped Rh perovskites with general formula La0.75A0.25Rh0.7Cu0.3O3 and La0.75A0.25Rh0.5Cu0.5O3 (A=Ca2+, Sr2+, Pb2+and Bi3+) were synthesized by solid-state methods and their crystallographic, magnetic, and electric properties investigated. Doping by divalent cations resulted in much lower cell volumes and octahedral distortions than doping with a trivalent oxide. The Pb2+ and Bi3+ (6s2) doped oxides exhibited the lowest magnetic moments and the highest activation energies. Magnetization curves are indicative of antiferromagnetic behavior. The addition of Ca2+, Sr2+, Pb2+and Bi3+cations to the A-site decreases the conductivity.© 2013, Elsevier Ltd.en_AU
