本文从理论上研究了外加电场在铁磁金属中诱导的磁振子拖拽效应，通过微观计算磁振子发射、吸收和被驱动电子散射所产生的力。结果表明，在较长弹性寿命的优良金属中，磁振子散射的贡献在较宽的温度范围内大于发射和吸收的贡献，因为后者由于磁振子的电子自旋翻转而具有相对的抑制因子，其中磁振子是交换相互作用能。讨论了包括磁振子阻力效应在内的自旋传递效率。
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 and absorption and scattering due to driven electrons. It is shown that magnon scattering contribution dominates over the emission and absorption ones in a wide temperature regime in good metals with long elastic lifetime, as the latter has a relative suppression factor ofdue to the electron spin flip by the magnon, whereis theexchange interaction energy. Spin-transfer efficiency is discussed including the magnon drag effect.
