Abstract
Induced modulation instability of backward volume spin waves in ferromagnetic films is investigated. It is found that the nonlinearity of the spin system of a ferromagnetic sample can greatly enrich the spectrum by excitation of spin waves at close frequencies and, in consequence, result in the appearance of a sequence of soliton-like pulses.
