Abstract

Magnon scattering studies can play a crucial role in revealing fundamental aspects of magnon physics. Due to the nonlinear nature of scattering, such studies are also important for applications ranging from traditional microwave signal processing to novel magnon-based computation. In this work, simulations employing realistic material parameters are used to demonstrate the tunable nature of magnon-based nonlinear properties. The changes are affected through modification of the dispersion relation of the magnetic system. It is demonstrated that the magnon nonlinear response is very sensitive to the sample film thickness while showing a relatively weaker dependence on saturation magnetization. Aside from the contributions to the fundamental understanding of magnons, the results presented are useful for establishing design rules for magnon-based applications.
