Synthesis and electrical transport property of (La0.7-x Yx) Ca0.3MnO3 ceramics / Nur Fitri Julirin

This report about the Colossal magnetoresistance ceramics with the nominal composition of (La0.7-x Yx) Ca0.3MnO3 were synthesis and their electrical transport property with the sample concentration of x=0.00, 0.05, 0.015 and 0.20. The samples were synthesized by solid-state reaction method. The sca...
