Abstract: | The magnetization dynamics in (100) single-crystal films with a cubic anisotropy has been studied by numerical simulation.
It has been shown that the additional (bifurcation) resonance caused by the bistability, i.e., two closely spaced equilibrium
magnetization states, appears upon in-plane magnetization along the hard axis. The change in the resonance region and the
corresponding dynamic regimes with a variation in the RF field or with a small detuning of the magnetizing field has been
investigated. The regular and chaotic precession regimes near the bifurcation resonance have been revealed. The states of
dynamic bistability have been found. |
