As is well-known, magnetostatic surface waves exhibit a strong effect of power saturation on their devices, and even in the magnetostatic volume wave devices this phenomenon is often observed, if a thin yttrium iron garnet film is used. These effects are due to a spontaneous transfer of motion from magnetostatic waves to spin waves. So saturation power level is studied based on Suhl's theory. Numerical results are found to be in good agreement with experimental data. Dependence of saturation power level on sample geometry and each of three fundamental magnetostatic modes is discussed.
