磁Skyrmion分箱

Magnetic skyrmion binning

Charles Kind, David Foster

摘要:

当自旋极化的电子流过磁性结构时,就会产生转移力矩。我们研究这种扭矩的影响Skyrmion和Skyrmion袋,任意整数拓扑度的Skyrmion结构,在薄铁磁薄膜。使用微磁模拟和分析,从著名的蒂勒方程,我们探讨了潜在的排序或分级skyrmions不同程度的机械。我们调查的适用性的Thiele方程的问题,这种性质,并推导出一个理论的skyrmion偏转有序的拓扑度。

英文摘要:

When spin polarised electrons flow through a magnetic texture a transfer torque is generated. We examine the effect of this torque on skyrmions and skyrmion bags, skyrmionic structures of arbitrary integer topological degree, in thin ferromagnetic films. Using micromagnetic simulations and analysis from the well known Thiele equation we explore the potential for sorting or binning skyrmions of varying degrees mechanically. We investigate the applicability of the Thiele equation to problems of this nature and derive a theory of skyrmion deflection ordered by topological degree.
