Abstract
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.
