Abstract
Ordinal excitations of three-magnon decay, modulation instability and four-magnon decay processes of magnetostatic surface waves propagating in a pure yttrium iron garnet film are investigated in accordance wit h the relationship between the magnetostatic wave frequency and the in ternal magnetic field. Onset of the modulation instability is realized as a result of modification of magnetostatic surface wave dispersion characteristics by a metallic ground plane.
