Abstract
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 defin ed maxima in the real part of ac susceptibility at the same temperature of the cusp in the zero field cooling curves corroborates cluster-glass behavi our.
