Abstract—The features of precession of the magnetic moment of a film near ferromagnetic resonance are
investigated which are due to the magnetic-moment nutation in the effective field and to the frequency-doubling
effect. The contribution to this precession from harmonics with frequencies which are multiples of the basic
resonance frequency is analyzed for a garnet ferrite film of the (111) type in a perpendicular bias magnetic field.
