论文摘要
在这项工作中,我们研究了多层纳米型中的天源核的振荡,这是系统中托管的天空数量的函数。当纳米射线中的所有天空矩阵具有相同的核心半径,并且在施加了垂直自旋极化电流后,放松过程就会朝着平衡构型进行,该构型伴随着Skyrmion核心的相干振荡,其频率依赖于Nananodot中存在的天才数量。此外,我们发现振荡频率与系统的总能量直接相关。
In this work we study the oscillations of the skyrmion cores in a multilayer nanodot as a function of the number of skyrmions hosted in the system. When all the skyrmions in the nanodot have the same core radius, and after applying a perpendicular spin-polarized current, a relaxation process takes place towards an equilibrium configuration that is accompanied by coherent damped oscillations of the skyrmion cores, whose frequency depends on the number of skyrmions present in the nanodot. Additionally, we found that the oscillation frequency is directly related to the total energy of the system.
