Herein, we report the dynamic susceptibility spectra of ferromagnetic spheres with diameters varying from 50 to 100 nm determined via micromagnetic simulations. The dynamic susceptibility spectra were calculated based on magnetization and the external field response in the frequency domain using Fourier transforms. The peak of the imaginary part of the dynamic susceptibility spectra, which indicates the resonance frequency of the ferromagnetic material, is interestingly near Kittel's resonance frequency.
