论文摘要
我们研究了抗磁性细磁盘中的天际构型和动力学。结果表明，Skyrmion获得了具有明确定义的振幅和频率的振荡动力学，可以通过自旋极化电流来控制需求。这种动态是强大的，因为两个半盘之间的接口不能显着改变动态。确实，尽管跨越了这个界面，Skyrmion仍然保持其振荡性。 Skyrmion发现这样做的方式是通过修改其核心区域形状，以使其总能量对几个周期的总能量不变。
We investigate skyrmion configuration and dynamics in antiferromagnetic thin disks. It is shown that the skyrmion acquires oscillatory dynamics with well-defined amplitude and frequency which may be controlled on demand by the spin-polarized current. Such dynamics are robust in the sense that an interface between two half-disks cannot change the dynamics appreciably. Indeed, the skyrmion keeps its oscillatory despite crossing this interface. The way skyrmion found to do that is by modifying its core region shape so that its total energy is unaltered for several cycles.
