Hoffmann, F. and Woltersdorf, Georg and Perzlmaier, K. and Slavin, A. N. and Tiberkevich, V. S. and Bischof, A. and Weiss, Dieter and Back, Christian (2007) Mode degeneracy due to vortex core removal in magnetic disks. Physical Review B 76 (1), 014416.
The mode spectrum of micrometer-sized ferromagnetic Permalloy disks, exhibiting a vortex ground state, is investigated by means of time-resolved scanning Kerr microscopy. The temporal evolution of the magnetization is probed after application of a fast in-plane field pulse. The lowest order azimuthal mode, a mode with only one diametric node, splits into a doublet as the disk diameter ...
