Using the analytical FMR theory, the real part of the surface impedance as dependent on the magnetic field and surface anisotropy is calculated for two types of ferromagnetic metals with different exchange‐conductivity parameters. The shapes of the obtained two sets of FMR spectra (including the main and surface resonance modes) differ considerably; the discussion of the cause of this effect points to a pronounced influence of the FMR cross‐over region.
