The first-order Suhl instability in a bismuth-substituted yttrium iron garnet (Bi-YIG) film is parametrically driven at the difference frequency of two microwave oscillators. Our results show that the onset of the instability occurs at lower threshold power when excited parametrically, and the power of the instability can be fed into other spin wave modes. Other nonlinear processes are also enhanced using parametric excitation.
