布洛赫畴壁弯曲振荡对自旋波的非弹性散射
Inelastic spin-wave scattering by Bloch domain wall flexure oscillations
摘要：
本文计算了磁薄膜中布洛赫畴壁（温特斯磁振子）弯曲振动对自旋波的非弹性散射。该方法是基于传播的自旋波的相互作用的动态新兴的电磁场所产生的移动不均匀的磁化结构（畴壁）。温特斯磁振子发射和吸收过程的自旋波散射几率随自旋波散射角的增大而增大。散射概率的角度依赖性基本上是强的磁振子吸收过程，允许区分这些基本的发射/吸收过程的实验。
英文摘要：
The calculations of the inelastic spin wave scattering by flexure vibrations of the Bloch domain wall (Winters magnons) in thin magnetic films are presented. The approach is based on the interaction of the propagating spin waves with the dynamical emergent electromagnetic field generated by the moving inhomogeneous magnetization texture (domain wall). The probability of the spin wave scattering for the Winters magnon emission and absorption processes essentially rises with the spin wave scattering angle increase up to 900. The angular dependence of the scattering probability is essentially stronger for the magnon absorption processes that allow distinguishing these elementary emission/absorption processes experimentally.
