Mechanism of Fast Axially--Symmetric Reversal of Magnetic Vortex Core (1212.2183v1)
Published 10 Dec 2012 in cond-mat.mes-hall and cond-mat.str-el
Abstract: The magnetic vortex core in a nanodot can be switched by an alternating transversal magnetic field. We propose a simple collective coordinate model which describes comprehensive vortex core dynamics, including resonant behavior, weakly nonlinear regimes, and reversal dynamics. A chaotic dynamics of the vortex polarity is predicted. All analytical results were confirmed by micromagnetic simulations.
