Abstract

Magnetic vortex is one of the interesting topic for the spin dynamics due to its attractive characteristic such as the high thermal stability and the small frequency dispersion. Most of studies on the magnetic vortex have been carried out by using circular-shaped ferromagnetic disk. So far, we have investigated the magnetic vortex confined in a triangular ferromagnetic dot and found some feature shown on triangular ferromagnetic dot such as the chirality of the vortex in the regular triangle can be controlled by the direction of the initialized in-plane magnetic field [1] and the resonant frequency of the vortex-core gyration motion in the triangular dot is higher than the circular one. In addition, we here report that the dynamics properties of vortex core is reconfigurable in a polygonal ferromagnetic dot due to its anisotropic shape.
