Electrical properties and enhanced room temperature magnetoresistance in La0.7Ca0.2Sr0.1MnO3/Pd composites prepared by chemical plating

► The La0.7Ca0.2Sr0.1MnO3/Pd composites were prepared successfully by chemical plating. ► Pd additions were uniformly distributed on the grain boundaries of the LCSMO grains. ► The value of MR exhibited dramatically with increase of plating time. ► When the plating time is 40 min, the MR value reaches the maximum value.
