Аннотация: For the first time characteristic modification of a spectrum of the exchange spin waves, caused by the first stop-band at a wave vector k b=?/(d1+d2) the magnon crystal formed by onedimensional modulation of the exchange or magnetization has been found by he spin-wave resonance (SWR) technique in multilayer structures "ferromagnet/Показать полностьюferromagnet" with N(d1+d2) thickness. It is shown that at transformation of a multilayer film after thermal annealing in a film of a single-phase alloy the given modification of a spectrum disappears.
