Excitation and propagation of short-wavelength exchange-dominated spin waves in garnet films with nonuniformity of the anisotropy field along the thickness of the film is considered. The paper includes experiments on propagation of pulses of spin waves through the film thickness, and experiments on conversion of spin waves into acoustic waves.
