斯格明子与基底的相互作用是研究纳米结构中的类粒子斯格明子时需要考虑的一个重要问题,它可能会强烈影响斯格明子的动力学并导致复杂的动力学现象。在这里,我们报告了类粒子斯格明子与铁磁层中的漏斗障碍物相互作用的电流驱动的动态行为。我们通过计算证明,由于斯格明子与漏斗之间的排斥相互作用,具有增强垂直磁各向异性的漏斗障碍物可用于修改斯格明子的动力学,这可能会产生几种重要的效应,包括斯格明子的压缩、堵塞、湮灭、引导运动和捕获。还发现漏斗障碍可以将传入的斯格明子流分成两个不对称流。此外,我们表明可以通过静态和动态方式通过漏斗障碍物捕获斯格明子。我们的结果有助于理解斯格明子与基底相互作用的动力学,并可以为传输通道中斯格明子流的控制提供指导。
The skyrmion-substrate interaction is an important issue to consider when studying particle-like skyrmions in nanostructures, which may strongly affect the skyrmion dynamics and lead to complex dynamic phenomena. Here, we report the current-driven dynamic behaviors of particle-like skyrmions interacting with the funnel obstacle in a ferromagnetic layer. We computationally demonstrate that a funnel obstacle with enhanced perpendicular magnetic anisotropy can be used to modify the dynamics of skyrmions due to the repulsive skyrmion-funnel interaction, which could generate several nontrivial effects, including the compression, clogging, annihilation, guided motion, and capturing of skyrmions. It is also found that the funnel obstacle can separate an incoming flow of skyrmions into two asymmetric flows. Moreover, we show that it is possible to capture skyrmions by the funnel obstacle in both static and dynamic ways. Our results are useful for understanding the skyrmion dynamics interacting with the substrate and could provide guidelines for the control of skyrmion flows in a transmission channel.
