Abstract:

The bottom of the spin-wave spectrum is examined for the case of a thin film magnetized in its plane. The bias field H sub b and wave number k sub b for the onset of first-order spin-wave instability at high microwave power is calculated. In addition, the critical thickness d sub c, at which the uniform mode saturation process changes from first to second order, is obtained. These results are in fairly good agreement with experiment.
