Abstract: The method and results of calculating the coefficient of transmission of a circular ultrasound wave through a multilayer ferromagnet/nonmagnet dielectric system with allowance for excitation of spin waves in magnetic layers are presented. The dependence of the resonance structure of the transmittance spectrum on the number of layers and the magnetic field strength has been studied.
