Abstract

The excitation spectrum of simple magnetic vortex state structures and eigenmodes of the system were analyzed. The images of excited magnetic eigenmodes up to three order obtained by means of a phase sensitive Fourier transform imaging technique were presented. It was found that both axially symmetric and symmetry breaking azimuthal eigenmodes were observed. The strong oscillations of the magnetization in the central part of the magnetic elements were also elaborated.
