Popis:	The problem of excitation of spin waves in a two-layer magnetic film with a sharp interface between the layers is solved on the basis of Slonchevskii equations. The equations describing spin wave excitation along the film thickness are derived. The results are limited to zeroth approximation in the smallness parameter ɛ, viz. the ratio of the energy of magnetic dipole forces to the anisotropy energy. The power dissipated by such oscillations is calculated.
