摘　　要：利用传递矩阵方法,计算了自旋轨道耦合对铁磁/半导体/绝缘体多层膜结构中隧穿性质的影响.结果表明,当半导体和铁磁体之间是绝缘接触时,体系的输运性质发生明显改变,同时出现了自旋反转效应.By using transfer matrix method, spin-dependent electron transport properties in ferromagnet/ semieonduetor/insulator hetero-junetion are investigated. When the eontaet between the ferromagnet and the semieonduetor is insulated, the transport properties are ehanged obviously, and spin flip effeet appears.
