Аннотация: The results of complex studies of structural-phase transformations and magneto-opticalproperties of nanocomposites (CoFeZr)x (MgF2)100􀀀x depending on the metal alloy content in thedielectric matrix are presented. Nanocomposites were deposited by ion-beam sputtering onto glassand glass-ceramic substrate. By studying the spectral and field dependences of the transversal Kerreffect (TKE), it was found that the transition of nanocomposites from superparamagnetic to theferromagnetic state occurs in the region of xfm~30 at%, that corresponds to the onset the formationof ferromagnetic nanocrystals CoFeZr with hexagonal syngony in amorphous dielectric matrix ofMgF2. With an increase of concentrations of the metal alloy for x > xfm, the features associatedwith structural transitions in magnetic granules are revealed in the TKE spectra. Comparison of thespectral and concentration dependences of TKE for nanocomposites on the glass and glass-ceramicssubstrates showed that the strongest differences occur in the region of the phase structural transitionof CoFeZr nanocrystals from a hexagonal to a body-centered cubic structure at x = 38 at.% on theglass substrates and at x = 46 at.% on glass-ceramics substrates, due to different diffusion rates anddifferent size of metal nanocrystals on amorphous glass substrates and more rough polycrystallineglass-ceramics substrates.
