Abstract

The substitution of Pr on the La site in La_1-xPr _xPb_0.3MnO₃ has been studied in order to probe into the physical mechanisms of colossal magnetoresistance (CMR) behavior. The magnetic order changes from a long-range order with x = 0.0 to a short-range nature with x = 0.7. The ferro-paramagnetic and metal-insulator transition temperature values decrease as Pr content increases. The highest MR ratio value is 16.9% for x = 0.0 against 41.6% for x = 0.7 in an applied field of 1 T. It is suggested that the mean ionic radius of the La-site ions may plays an important role on the CMR effect.
