Controlled vortex core switching in a magnetic nanodisk by a rotating field
arXiv:0705.2046 · doi:10.1063/1.2770819
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.
