In the present study, the rotation and switching of a vortex core in submicron-size square dots were numerically analyzed by micromagnetic simulation. This study clarified that the eigenfrequency of the vortex core is strongly dependent on the magnetostatic energy and that rapid switching can be realized by circularly polarized fields with practical amplitudes at the corresponding eigenfrequency. The inductive detection of vortex core rotation, which can distinguish vortex core polarity, was successfully demonstrated and the structural design of the detector was optimized.
