Abstract :
The aim of this work was to perform MSW (magnetostatic wave) ring experiments at lower frequencies where three wave processes are allowed and examine the combined effects of the four- and three-wave processes on the NL (nonlinear) response. Three entirely new phenomena have been discovered: (1) a clear dual modulational instability response that involves three- as well as four-wave processes, (2) the self-generation of quasi-single or solitary pulses in the ring, and (3) a chaotic power frequency (PF) spectrum over the entire MSW band.
