Taking into account the electron spin mobility, the paper considers the numerical solution to the equation for nonequilibrium spin polarization at the boundary of a magnetic contact with a current formed by two ferromagnets. The frequencies of spin injection radiation are calculated. It is shown that at a certain current density exceeding the threshold value, these frequencies lie in the terahertz frequency range. It was found that for the same terahertz frequency range, even for small values of the difference in the mobility of electrons with spin up and down, the current density can be two orders of magnitude lower than the current density with the same mobility.

考虑电子自旋迁移率的磁跃迁中的注入平衡自旋极化

考虑到电子自旋迁移率，本文考虑了在由两个铁磁体形成的电流进行磁接触时，非平衡自旋极化方程的数值解。计算自旋注入辐射的频率。结果表明，在一定的电流密度超过阈值时，这些频率位于太赫兹频率范围内。发现对于相同的太赫兹频率范围，即使对于具有自旋向上和向下旋转的电子的迁移率的差的较小值，电流密度也可以比具有相同迁移率的电流密度低两个数量级。
