Electric Pulse Induced Resistive Switching of La1-xCaxMnO3 at High Magnetic Field and Low Temperature
Source abstract
Abstract
对La 1- x Ca x MnO 3 ( x =0.3, 0.5)多晶材料的巨磁电阻效应及低温高磁场下的电脉冲诱导电阻可逆变化(EPIR)效应进行了研究, 并对两者之间的区别进行了分析. 实验结果表明, La 1- x Ca x MnO 3 ( x =0.3和0.5)多晶材料在低温高磁场下仍具有EPIR效应, 电阻在相同电脉冲下的变化率不随温度和施加磁场与否发生变化, 表现出不同于巨磁电阻效应的变化规律. 结合之前的研究结果, 发现巨磁电阻效应是由于磁场造成磁矩的有序并继而造成电子的退局域化引起的, 而EPIR效应则是由于电脉冲诱导氧离子迁移, 导致载流子浓度变化引起的.
