摘要：

Dispersion and attenuation of non-linear surface magnetostatic waves (MSSW) propagating in thin yttrium-iron-garnet (YIG) ferrite films have been studied both experimentally and theoretically. They were defined from the amplitude and phase alterations of the wave as it traveled along the ''non-equilibrium'' part of the film. At the border of such a non-equilibrium part the wave power is equal to the threshold value. The value for the threshold power is defined by the first- and second-order parametric decay processes for the MSSW.
