Abstract: The resonance motion of the magnetization of thin cylindrical and parallelepiped micro- and nanodots has been studied theoretically and experimentally. Analytical expressions for the external-field dependence of the resonance frequency of the vortex-structure oscillations have been derived taking into account the inertial and damping coefficients. The external-field dependence of the damping parameter has been found theoretically. The influence of the effective mass of a magnetic vortex on its low-frequency dynamics has been discussed.
