摘要：
Polycrystalline samples of the mixed-valence perovskite-type manganites Sm0.35Nd0.35M0.3Mn1-xFexO3 (M = Pb, Cd; x = 0, 0.1) have been synthesised and their magnetic and transport properties studied. Magnetic measurements show that T-C values decrease considerably with the presence of cadmium or iron. Colossal magnetoresistance has been shifted to lower temperatures. Values of magnetoresistance near to 40% have been obtained. The presence of defined maxima in the real part of ac susceptibility at the same temperature of the cusp in the zero field cooling curves corroborates cluster-glass behaviour.
