摘要:

我们报告的微磁学数值模拟研究相邻的skyrmions在窄宽度的纳米带之间的动态耦合。我们探讨了耦合的回旋模式和它们的特征色散的相邻skyrmions之间的间距。重要的是,垂直磁场的应用允许控制/修改耦合模式的色散。耦合skyrmion回转模式提供了一种新型的有效的,可靠的,快速的,低功耗的信息信号传播窄宽度直和弯曲的纳米带,主要是由个别纳米尺度skyrmion之间的交换相互作用驱动。

英文摘要:

We report on a micromagnetic numerical simulation study of dynamic couplings between neighboring skyrmions in narrow-width nanostrips. We explored the coupled gyration modes and their characteristic dispersions in terms of the interdistance between the neighboring skyrmions. The application of perpendicular magnetic fields, importantly, allows for control/modification of the dispersion of the coupled modes. Coupled skyrmion gyration modes provide a new type of efficient, reliable, fast, low-power-consumption information-signal propagation in narrow-width straight and curved nanostrips, as driven predominantly by the exchange interaction between individual nano-scale skyrmions.
