摘要：
Several models in which a microwave radiation of the frequency omega1 arises from the bottom of spin-wave spectrum under condition of parametric resonance of magnons of the frequency omega(p)/2 are considered. Weak radiation of the frequency omega2 = omega(p) + omega1 has been detected in thin ferrite film. This radiation can be treated in favour of both the theory of kinetic instability and the thermodynamic theory of parametric resonance of magnons. Possibility of Bose condensation of nonequilibrium magnons is discussed.
