磁泡自旋转移矩的Skyrmion数依赖性

Skyrmion-number dependence of spin-transfer torque on magnetic bubbles

Yuta Yamane, Jairo Sinova

摘要:

从理论上研究了作用在磁泡上的自旋转移矩的Skyrmion数依赖性。磁泡的skymrion数可以取任何整数值,这取决于其圆周上的磁性轮廓和磁泡的大小。我们发现,当Skyrmion数的绝对值偏离1时,气泡相对于电荷流的横向运动被大大抑制,而纵向运动则不太敏感。

英文摘要:

We theoretically study the skyrmion-number dependence of spin-transfer torque acting on magnetic bubbles. The skymrion number of magnetic bubbles can take any integer value depending on the magnetic profile on its circumference and the size of the bubble. We find that the transverse motion of a bubble with respect to the charge current is greatly suppressed as the absolute value of skyrmion number departs from unity, whereas the longitudinal motion is less sensitive.
