通过微观计算，由镁发射/吸收/吸收/吸收和散射引起的镁磁力计算，通过驱动电子引起的力计算，由铁磁金属中施加的电场引起的镁阻力效应。结果表明，镁散射的贡献在较高的金属中以较长的弹性寿命$ \ taue $为主，因为后者的相对抑制因子为$（\ deltasd \ taue）^{ - 2} $，因为$ \ $ \ $ \ s $ \ ssd $ \ s s s s s s sd sd $ \ sed s s s s sd sd $ \ sd $ \ s sd sd $ \ sd $ \ sd $ \ sd $ \ sd $ \ sd $ \ sd $ \ s sd。讨论了自旋转移效率，包括木纳阻力效应。
Magnon drag effect induced by an applied electric field in ferromagnetic metals is theoretically studied by a microscopic calculation of the force on magnons arising from magnon emission/absorption and scattering due to driven electrons. It is shown that magnon scattering contribution dominates over the emission/absorption one in a wide temperature regime in good metals with long elastic lifetime $\taue$, as the latter has a relative suppression factor of $(\Deltasd\taue)^{-2}$ due to the electron spin flip by the magnon, where $\Deltasd$ is the $sd$ exchange interaction energy. Spin-transfer efficiency is discussed including the magnon drag effect.
