我们研究了二维电子气(2DEG)中存在自旋-轨道耦合时的自旋和电荷输运现象，该耦合与两个平行磁化的理想铁磁导线相连。结果表明，自旋极化态通过二维电子气的输运依赖于二维电子气平面垂直于它的坐标系中磁化强度的绝对方向。电导也是各向异性的。
We explore spin and charge transport phenomena in a two-dimensional electron gas (2DEG) in presence of spin-orbit coupling connected to two ideal Ferromagnetic leads with parallel magnetization. It is shown that the spin polarization transported through the 2DEG depends on the absolute direction of magnetization in a coordinate system defined by plane of 2DEG and normal to it. Conductance is also shown to be anisotropic.
