Abstract

Standing exchange spin-waves spectrum of Ni80Fe20/Dy20Co80/Ni80Fe20 magnetic sandwiches was in- vestigated by the spin-wave rasonance technique. The layer of the amorphouse ferrimagnetic alloy has precompensation composition, therethore its magnetic structure provided positive value of the exchange coupling between the ferromagnetic layers. It was shown that spin modes of SWR specrum whitch ac- cording to the Kittel's ratio Hr(n) n2 are the standing acoustic exchange spin oscillations. It was determined, that spin modes of optical satellites of the SWR acoustic peaks are characterized by another ratio Hr(n) n5/2.
