Nonlinear precession of magnetization in a ferrite-garnet film of the (100) type

The dynamics of stationary resonance precession during perpendicular biasing of a ferrite-garnet film of the (100) type in a wide range of resonance frequencies and amplitudes of an alternating field is studied on the basis of numerical solution of the magnetization motion equations. The influence of the crystallographic and growth anisotropy on the trajectories of precession motion is studied. A new type of symmetric precession trajectories is found and the states of dynamic bistability are revealed.
