Bifurcation magnetic resonance in films with differently oriented crystallographic axes

Bifurcation magnetic resonance in films with differently oriented crystallographic axes Abstract The magnetization dynamics in single-crystal films with cubic anisotropy has been investigated based on numerical simulation. It is shown that the application of an in-plane bias magnetic field along hard magnetization axes gives rise to an additional (bifurcation) resonance, which is due to the existence of bistability, i.e., two closely located equilibrium magnetization states. The specific features of bifurcation resonance are revealed in films with the three main crystallographic orientations: (100), (110), and (111). Changes in the resonance range and corresponding dynamic modes with a change in the ac field frequency are investigated. States of dynamic bistability and multistability are obtained in the bifurcation resonance range. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Crystallography Reports Springer Journals

Abstract

Abstract The magnetization dynamics in single-crystal films with cubic anisotropy has been investigated based on numerical simulation. It is shown that the application of an in-plane bias magnetic field along hard magnetization axes gives rise to an additional (bifurcation) resonance, which is due to the existence of bistability, i.e., two closely located equilibrium magnetization states. The specific features of bifurcation resonance are revealed in films with the three main crystallographic orientations: (100), (110), and (111). Changes in the resonance range and corresponding dynamic modes with a change in the ac field frequency are investigated. States of dynamic bistability and multistability are obtained in the bifurcation resonance range.
