我们研究了横向自旋注入几何中居里温度的增加，<?format ?>铁磁（Ga，Mn）As注入器和检测器接触由薄铁膜覆盖。因为<?format ?> Fe和（Ga，Mn）Asgets之间的层间耦合增强了近100<?format ?> (Ga，Mn）As膜。邻近效应的使用可能为自旋电子器件的实际实现铺平道路。
We investigate the increase of the Curie temperaturein a lateral spin injection geometry where <?format ?>the ferromagnetic (Ga,Mn)As injector and detector contacts are capped by a thin iron film. Because <?format ?>of interlayer coupling between Fe and (Ga,Mn)Asgets enhanced by nearly 100% for the thinnest <?format ?>(Ga,Mn)As films. The use of the proximity effect might pave the way for practical implementation of spintronic devices.
