Controlled vortex core switching in a magnetic nanodisk by a rotating field

Abstract

The switching process of the vortex core in a Permalloy nanodisk affected by a rotating magnetic field is studied theoretically. A detailed description of magnetization dynamics is obtained by micromagnetic simulations.
