This work deals with the nonlinear magnetic dynamics in a thin ferromagnetic film under the influence of an alternating circular magnetic field. Two main precession modes were observed and the areas of their existence depending on the magnitude of the constant magnetic field, the frequency and amplitude of the alternating magnetic field and the magnitude of the magnetic anisotropy of the film material were outlined. Magnetization reversal diagrams, time dependencies and phase portraits of the magnetic dynamics of the film depending on the parameters of the external magnetic field were constructed. Keywords: ferromagnets, magnetocrystalline anisotropy, magnetization switching, modes of magnetic oscillations and precession.
