Аннотация: The standing spin-wave spectrum was studied by spin-wave resonance in three-layer Ni80Fe20/DyxCo1 - x/Ni80Fe20 films with an amorphous interlayer of DyCo alloy in the region of compensation compositions. It is shown that the spin-wave resonance (SWR) spectrum in the geometry k parallel to M is observed only for a planar system withПоказать полностьюa DyCo layer of precompensation composition. In the k perpendicular to M geometry, the SWR spectrum was observed for the DyCo systems with both pre- and postcompensation compositions. The exchange stiffness was analyzed as a function of the DyCo layer thickness to formulate a model of microheterophase structure for amorphous DyCo alloys in the compensation region, where the magnetic microstructure accounts for the dynamic and static magnetic characteristics of these materials.
