The combination of parametric pumping and spin-transfer torque is a powerfulapproach that enables high-level control over magnetic excitations in thin-filmferromagnets. The excitation parameters, such as pumping power and externalfield strength, affect the instabilities of individual magnon modes. Wetheoretically explore how the simultaneous effects of parametric pumping andspin transfer torque influence these magnetic instabilities in a thin-filmferromagnet. Within the Landau-Lifshitz-Gilbert framework, we performmicromagnetic simulations of magnon excitations in yttrium iron garnet bypumping, spin transfer torque, and a combination of the two. We find thatconsistent with experimental results, the magnitude and direction of thespin-transfer torque tune the parametric instability thresholds.
