Abstract

Spectra of electromagnetic emission of frequencies ≃ ω₁, 2ω₁, 3ω₁where ω_i is the bottom of the spin-wave band have been studied in yttrium iron garnet at temperatures of liquid nitrogen and liquid helium. The spin-wave system was strongly excited by parallel pumping with microwaves of frequency ω_p 2ω₁. Line shapes and frequency shifts of the emission depend on temperature, static magnetic field, pump power and time duration of the pump pulse. Discussion of obtained results is given.
