Application of Ferromagnetic Resonance Method to Study of Multilayer Nanostructures

The ferromagnetic resonance spectra of multilayer nanostructures synthesized from magnetic layers based on amorphous Co45Fe45Zr10 and nonmagnetic layers of the amorphous semiconductor α-Si have been experimentally studied. It is shown that the character of the spectrum depends strongly on thicknesses of magnetic and nonmagnetic layers and the structure of the boundary layer. The resonant fields are calculated within the effective-medium approximation. In some cases, the calculation results describe well the experimental data.
