High-frequency properties of multilayer systems based on the (Co_(41)Fe_(39)B_(20))_x(SiO_2)_(100-x) and (Co_(45)Fe_(45)Zr_(10))_x(Al_2O_3)_(100-x) nanocomposites

摘要

New {[({[(Co_(41)Fe_(39)B_(20))_x(SiO_2)_(100-x)]/[(Co_(41)Fe_(39)B_(20))_x(SiO_2)_(100-x)+O_2]}_(178) and {[(Co_(45)Fe_(45)Zr_(10))_x(Al_2O_3)_(100-x)]/[(Co_(45)Fe_(45)Zr_(10))_x(Al_2O_3)_(100-x)+O_2]} 300 multilayer heterogeneous structure has been obtained by ion-beam sputtering method. Magnetostatic and magnetodynamic properties and the structure of the nanocomposites have been investigated. It was shown that, the oxidized interlayer composite adding lead to suppression of perpendicular magnetic anisotropy component. A change in the magnetic structure of the composites, which determines the change in the frequency dependence of the real (μ~/) and imaginary (μ~(//)) parts of the complex permeability.
