我们用微磁模拟方法研究了丝上Skyrmion磁区的自旋注入驱动。我们发现，当自旋流注入到Skyrmion区的垂直轴上时，Neel型和Bloch型Skyrmion区都以倾斜的方向被驱动。从磁化方向和Skyrmion磁区的磁区-壁结构分析了驱动方向。(C)2017日本应用物理学会
We investigate the spin-injection driving of skyrmion domains on a wire using micromagnetic simulations. We find that both Neel- and Bloch-type skyrmion domains are driven in oblique directions when the spin current is injected into the vertical axis of the skyrmion domains. The driving direction is analyzed from the magnetized direction and the domain-wall structure of the skyrmion domains. (C) 2017 The Japan Society of Applied Physics
