Abstract

Spin-wave instability threshold under multiple drive excitations is studied in an yttrium iron garnet sphere at 4.2 K. Both a static magnetic field and a parallel RF field are applied along the [1 1 1] direction. Another perpendicular RF field excites magnetostatic modes through the first-order Suhl process. Interactions between spin-waves and magneostatic modes cause a change of instability thresholds.
