The dynamic susceptibility spectra of a soft ferromagnetic nanodot supporting a vortex-type magnetic configuration is studied in the frequencyrange 0.1–20 GHz bymeans of dynamic micromagnetic simulations. The frequency evolution of the detected magnetic excitations as a function of both dot radius (40
