摘要

本研究讨论了自旋波的方位角模式和涡旋核反转与弯曲模式的相互作用。用扫描透射x射线显微镜观察了坡莫合金圆盘的涡旋核反转，并用微磁模拟对其进行了分析。实验和仿真结果表明，在相互作用中观察到的不对称性是由一个占主导地位的三维开关机制造成的。

The third dimension: Vortex core reversal by interaction with ‘flexure modes’

This study discusses the interactions of azimuthal spin wave modes and vortex core reversal with flexure modes. Vortex core reversal in Permalloy discs is observed by scanning transmission X-ray microscopy and analyzed by micromagnetic simulation. Experimental and simulation results indicate that there is a dominant 3D switching mechanism responsible for the asymmetry observed in the interactions.
