The spin wave absorption spectra are obtained by a simultaneous solution of the Maxwell equation and the Gilbert equation considering the boundary condition of electromagnetic wave and magnetization in the film surfaces. The physical parameters that influence the absorption energy are thickness, exchange stiffness constant, surface magnetic anisotropy, magnetization, damping factor, electric resistivity of the thin film. We investigated how these parameters affect the resonance field, the linewidth and the intensity of the spin wave spectrum.
