Аннотация
The parametric instability threshold for the magnon sysem in a transverse microwave field and a longitudinal rf field is studied theoretically under the condition of combined resonance and beyond it. When second-order Suhl instability is taken into consideration, the dependence of the combination parametric resonance threshold on the frequency and amplitude of the rf field displays peculiarities and is not reduced to the results of longitudinal pumping.
