论文摘要
在本文中，研究了自旋波和磁涡之间的相互作用。我们发现三种类型的木片散射：偏斜散射，对称侧偏转和背部反射，它们与涡流中分别与磁性拓扑，能量密度分布和线性动量转移扭矩相关联。 Vortex核心表现出两种翻译模式：固有的圆形模式和强制椭圆模式，可以基于旋转波的永久和周期性的磁通旋转转移扭矩效应来激发。最后，我们提出了一个基于涡流的自旋波阀，其中通过不均匀性调制，我们访问对相移的任意控制。
In this paper, the interplay between spin wave and magnetic vortex is studied. We find three types of magnon scatterings: skew scattering, symmetric side deflection and back reflection, which associate with respectively magnetic topology, energy density distribution and linear momentum transfer torque within vortex. The vortex core exhibits two translational modes: the intrinsic circular mode and a coercive elliptical mode, which can be excited based on permanent and periodic magnon spin-transfer torque effects of spin wave. Lastly, we propose a vortex-based spin wave valve in which via inhomogeneity modulation we access arbitrary control of the phase shift.
