摘要：
The effects of Eu-doping in the A-site on the magnetic and magnetoresistive properties of La0.65-xEuxCa0.35MnO3 (x = 0, 0.05, 0.10, 0.15) bulk samples have been investigated. All samples have a single perovskite structure. The Curie temperature TC decreases with increasing Eu content from 268 K for x = 0 to 141 K for x = 0.15. The magnetoresistivity increases with increasing Eu content. Upon an application of a magnetic field of 2.0 T the maximum magnetoresistivity of 97.3% for the La0.50Eu0.15Sr0.35MnO3 was obtained. It provides an effective way to obtain the high magnetoresistance in the polycrystalline manganites.
