The CoP-based layered magnetic films, what is more the every layer has certain atomic and chemical structure, were studied by spin-resonance method. The covers were synthesized two type: magnonic crystals (amorphous Co(P)/fcc Co(P))N and gradient Co(P)-based films and they allow us to observe two different modification SWR spectrum. In one case it is SWR spectrum like Hn(n)~n2 when modification is result from created first stop-zone of a magnonic crystal. In the second case the dependence of resonance fields Hn of the spin-wave modes on mode number n has the form Hn(n)~n2/3. The thermal annealing gives rise to the crystallization (the amorphous state transfers to fcc) and cases the transformation of layered films to films of monophase Co-P-based alloys, this process declares itself in changing SWR spectrums form and in the spectrum modification like “exchange kink”
