Influence of Si on the magnetic properties of multilayer nanostructures with composite magnetic layers

The static and dynamic properties of multilayer structures [(Co45Fe45Zr10) m (Al2O3)100 − x ] x /(a-Si) y with various magnetic phase concentrations and for different thicknesses x and y were measured. It was shown that for samples with comparatively thick composite layers and thin interlayers (x/y > 8), the silicides that form play no significant role and the magnetic properties are determined by the composites. With an increase in the thickness of the interlayers, more granules form silicides. This reduces the concentration of the magnetic phase, influencing the samples’ resonance fields and magnetization.
