Magneto-electric Behaviors of La0.67-xNdxSr0.33MnO3 System

Abstract
通过M-T曲线、ESR曲线、红外光谱、拉曼光谱、ρ-T曲线和MR-T曲线的测量,研究了La(0.67-x)NdxSr(0.33)MNO3(x=0.10,0.20,0.30,0.40,0.50)样品的磁电性质.实验结果表明:随着Nd掺杂的增加,样品的磁结构从长程铁磁有序向自旋团簇玻璃态、反铁磁态转变;当x=0.30、0.40时发生相分离,且x=0.40样品的ZFC曲线随温度升高在160K左右突然跌落,出现少见的“肩膀”;样品的电行为随着Nd掺杂的增加发生变化.样品的磁电行为和CMR效应来源于Nd掺杂引起的次晶格不同耦合和与自旋相关的界面隧穿效应.
