Nonlinear magnetostatic surface waves pulse propagation in ferrite-dielectric-metal structure

The influence of the modulation and parametric four-magnon instabilities on the propagation of magnetostatic surface wave (MSSW) pulses in a delay line configuration has been experimentally studied in a ferrite-dielectric-metal structure. It was possible to distinguish the influence of both instabilities by changing the dispersion properties of the exploited device. The contribution of additional MSSW continuous wave and pulsed signals on the propagation of MSSW pulses has been also considered.
