论文摘要
移动的磁性天空表现出横向偏转。这种所谓的Skyrmion Hall效应已通过Thiele方程来解释。在这里，我们基于封闭天空映射的域墙的动力学来对Skyrmion Hall效应提供另一种解释。我们将域壁段旋转诱导的局部旋转与Skyrmion芯的移位联系起来，从而解释了微磁性水平的Skyrmion Hall效应。在我们的直觉解释上，我们还表明，可以通过结合自旋转移和自旋轨道扭矩来抑制天堂厅的效果，从而消除了利用设备中的天空的主要障碍。
A moving magnetic skyrmion exhibits transverse deflection. This so-called skyrmion Hall effect has been explained by the Thiele equation. Here, we provide an alternative interpretation of the skyrmion Hall effect based on the dynamics of domain walls enclosing the skyrmion. We relate the spin-torque-induced local rotation of the domain wall segments to the shift of the skyrmion core, explaining the skyrmion Hall effect at the micromagnetic level. Bases on our intuitive interpretation, we also show that the skyrmion Hall effect can be suppressed by combining the spin-transfer and spin-orbit torques, whereby removing the major obstacle to utilizing skyrmions in devices.
