| Abstract: | Precession of magnetization in a perpendicularly magnetized ferromagnetic film exposed to a circularly or linearly polarized
small-amplitude high-frequency magnetic field is studied analytically and numerically. The possibility of autoresonance excitation
of a highly nonlinear uniform precession of magnetization and of control over this motion by slowly varying the resonance
field or frequency of the high-frequency field is demonstrated. |
