我们报告说,一个基态自旋配置的铁磁纳米线缺口周围可以有对称或不对称的横向畴壁结构取决于缺口的几何形状通过微磁学模拟与缺口纵横比的系统变化。非对称的偏心畴壁结构在一定的缺口纵横比范围内变得稳定。
We report that a ground state spin configuration around a notch of ferromagnetic nanowires can have either symmetric or asymmetric transverse domain wall structure depending on the notch geometry by means of micromagnetic simulation with a systematic variation in the notch aspect ratio. An asymmetric off-centered domain wall configuration becomes stable for a certain range of the notch aspect ratio.
