Popis:	It is demonstrated that the misalignment of dispersion curves for the spin-wave resonance (SWR) spectra under perpendicular and parallel (with respect to the film plane) orientations of a constant magnetic field is reduced when the frequency of an SHF field is increased. It is found that the main factor driving the increase in the curve slope under a perpendicular orientation is related to the transition of the fixation layer from the state of a reactive medium to the state of a dispersive one. It is shown that a dispersion curve plotted for an orientation under which the fixation layer becomes a dispersive medium should be used in order to determine correctly the exchange interaction constant and the exchange rigidity based on the SWR spectrum.
