Resonance Modes of TwoLayer ExchangeCoupled Ferromagnetic Film

Ferromagnetic and spinwave resonances in twolayer exchangecoupled ferromagnetic films have been investigated numerically at different intensities of a magnetic field when it is directed in parallel or perpendic� ular to the film plane. Layers of the film have finite thicknesses and possess anisotropy of the easyplane and easy� axis types. It has been shown that at a nonzero parameter of interlayer exchange coupling the dynamic component of magnetization upon ferromagnetic resonance is distributed nonuniformly across the film thickness. Its change has been described when the external magnetic field decreases from the saturating field to zero.
