Spin Wave Excitations of the Interacting Two-Dimensional In-Plane Nano-Vortices

Languages of publication
The aim of this work is to study spin-wave excitations in the row of interacting two-dimensional nanodots in the vortex state. We use a discrete dipole model taking into account the nearest-neighbour exchange and dipolar interactions. Magnetic configuration of each dot is assumed to form an in-plane vortex (circular magnetization). We examine the dependence of frequencies and profiles of spin-wave modes vs. the dipolar-to-exchange interaction ratio and the dot separation. Special attention is paid to some particular modes: lowest-frequency azimuthal modes and the fundamental mode, an analogue of the uniform excitation. Some conclusions regarding the influence of the size of dots the row consists of as well as the chirality of neighbouring vortices are provided too.
