Microwave Bistability in a Nonlinear Film Ferromagnetic Resonator

摘要

Bistability inherent in the interactionofthe microwave radiation and a film ferromagentic resonator is experimentally investigated in the presence of ferromagnetic resonance. It is shown that the bistabiltiy is due to the resonator frequency shift and the intrinsic nonlinearity of the resonance observed at high amplitudes of the magnetization precession. Results of measurements are interpreted in terms of the dispersion-absorption model of bistability.
