Collective dynamics of magnetic vortices in an array of interacting nanodots
Abstract
The lift of the degeneracy of the resonance frequency of motion of the core of a magnetic vortex in a square array of nanodots has been experimentally detected. The appearance of a frequency multiplet has been theoretically explained. It has been shown that a reason for the lift of degeneracy can be the magnetostatic interaction between nanodots.
