Nonlinear properties of short-wavelength exchange-dominated spin waves in ferrite films have been studied experimentally. Collinear splitting of exchange spin waves into two waves has been observed. An yttrium-iron-garnet film with smooth variation of the uniaxial anisotropy field through the film thickness has been used for the experimental study. Nonuniformity of the film provided both the linear excitation of short-wavelength pumping wave and the detection of the radiation caused by the parametrically excited waves.
