Duffing oscillation-induced reversal of magnetic vortex core by a resonant perpendicular magnetic field
Nonlinear dynamics of the magnetic vortex state in a circular nanodisk was studied under a perpendicular alternating magnetic field that excites the radial modes of the magnetic resonance. Here, we show that as the oscillating frequency is swept down from a frequency higher than the eigenfrequency,...
