Abstract :
The reversal of magnetostatic volume wave (MSVW) group velocity caused by parametric interaction of two MSVWs propagating in a garnet film placed in a uniform harmonically modulated external magnetizing field was investigated experimentally. MSVW conversion efficiency of up to a few percent and frequency shift of up to 300 MHz were obtained
