摘要

我们用微霍尔探头研究了对称性降低的微磁性物体的涡旋动力学。将直径为1 μm的类似吃豆人的纳米点直接放置在霍尔探针上，信号呈带阻红色。我们发现，在77 K的磁化反转特性上，涡旋成核和湮灭以及- c态的产生/湮灭是清晰可见的。实验结果与微磁模拟结果吻合较好。

Nucleation and annihilation of magnetic vortices in Pacman-like nanodots observed by micro-Hall probes

We have used micro-Hall probe for the study of vortex dynamics in micromagnetic objects with lowered symmetry. The Pacman-like nanodot of the diameter of 1 μm was placed directly on the Hall probe and the signal was red in band resistance configuration. We show that the vortex nucleation and annihilation, as well as s-and c-state creation/annihilation are clearly visible on the magnetization reversal characteristics at 77 K. The experimental characteristics is in good agreement with the one calculated by micromagnetic simulations.
