Regular and chaotic vortex core reversal by a resonant perpendicular magnetic field
arXiv:1302.2594 · doi:10.1103/PhysRevB.88.014432
Abstract
Under the action of an alternating perpendicular magnetic field the polarity of the vortex state nanodisk can be efficiently switched. We predict the regular and chaotic dynamics of the vortex polarity and propose simple analytical description in terms of a reduced vortex core model. Conditions for the controllable polarity switching are analyzed.
