论文摘要
自旋波和磁纹理是磁系统中的两个基本激发，它们的相互作用导致磁性丰富。通过使用自己的集体坐标来描述自旋波和磁纹理，我们发现它们作为在相互电磁场中传播的经典颗粒相互作用。基于这个统一的集体坐标模型，我们发现偏斜散射和侧跳可能是随着旋转波穿过磁纹理而发生的。偏斜的散射与纹理的磁拓扑相关，而侧跳则与纹理的总磁化相关。我们通过研究跨拓扑磁性天空和拓扑上琐碎的磁性气泡的旋转波轨迹来说明偏斜散射和侧面跳跃的概念。
Spin wave and magnetic texture are two elementary excitations in magnetic systems, and their interaction leads to rich magnetic phenomena. By describing the spin wave and the magnetic texture using their own collective coordinates, we find that they interact as classical particles traveling in mutual electromagnetic fields. Based on this unified collective coordinate model, we find that both skew scattering and side jump may occur as spin wave passing through magnetic textures. The skew scattering is associated with the magnetic topology of the texture, while the side jump is correlated to the total magnetization of the texture. We illustrate the concepts of skew scattering and side jump by investigating the spin wave trajectories across the topological magnetic Skyrmion and the topologically trivial magnetic bubble respectively.
