Spectra of' electromagnetic emission of frequencies Th w?, 2w3 and 3cu3, where wj is the bottomof the spin-wave band have been sttrdied in yttrium iron garnet at temperatures of' liquid nitrogen and liquid helium. The spin-wave system was strongly excited by parallel pumping withmicrowaves of frequency w. >2ws. Line shapes and frequency shifts of the enaission depend ontemperature, static magnetic field, pLlIIlp power and time duration of the pump pulse. Discussionof obtained results is given.
