A calculation is made for the high-power instability of the Z-directed spin waves in a thin insulating ferromagnetic film. For complete pinning, the critical field is found to be (γh)2=Δn3n2π2[93(ωM+13ωexa2kn2)]−1. The calculation is also made for the critical field, assuming a mixed boundary condition.
