基于自旋电流和电荷电流的守恒定律，我们建立了包含非共线磁化铁磁元件的电子电路中的自旋相关输运理论。该理论大大简化了复杂铁磁-正常金属系统输运性质的计算。我们以一种新型的三端器件为例来说明这一理论。
We formulate a theory of spin dependent transport in an electronic circuit involving ferromagnetic elements with noncollinear magnetization which is based on the conservation of spin and charge current. The theory considerably simplifies the calculation of the transport properties of complicated ferromagnet-normal metal systems. We illustrate the theory by considering a novel three-terminal device.
