Switching phenomena in easy-plane ferromagnets and magnetic nanodots
Some generic properties of switching of the vortex polarity dynamics will be discussed.
The following issues will be considered.
1 Switching of the vortex polarity by ac magnetic fields and spin-polarized electrical currents in easy plane ferromagnets and magnetic nanodots. Comparative study.
2. Conservation laws for vortex dynamics. Rotating frame of reference.
3. Interacting magnon mode approach.
4. Vortex core in easy plane ferromagnets under an action of ac magnetic fields as a parametrically driven Duffing oscillator.
