Abstract: | The equations of the precession dynamics of the magnetic moment have been analyzed to study the specific features of the low-frequency ferromagnetic resonance corresponding to magnetic biasing along the hard magnetic axis of a film with an in-plane uniaxial anisotropy. It has been found that the precession trajectories exhibited a complicated hopping behavior and the resonance curve was asymmetric. This behavior and the asymmetry were due to an angular bistability arising from the presence of two symmetric angular positions of equilibrium near the anisotropy field. |
