“…These include structures based on composite nanolayers with CoFeB ferromagnetic clusters, in which a magnetoresistance of about 6% is achieved. 5 This suggests that when the material of the non-magnetic layer, thicknesses of the magnetic/non-magnetic layer and the geometry of the MLs change, the GMR value may increase several times. The nonlinear electromagnetic properties of such multilayer nanostructures depend not only on the volume ratio of the magnetic and nonmagnetic phases but also on their structure and interphase interactions at the interfaces.…”

“…Therefore, steps are being taken to find the values of a giant magnetoresistance of sufficient magnitude in less perfect but easier to obtain structures. These include structures based on composite nanolayers with CoFeB ferromagnetic clusters, in which a magnetoresistance of about 6% is achieved 5 . This suggests that when the material of the non‐magnetic layer, thicknesses of the magnetic/non‐magnetic layer and the geometry of the MLs change, the GMR value may increase several times.…”

The multilayer nanostructures have drawn attention in fields from spintronics to microwave electronics. The purpose of this work was to determine the composition of individual layers and to control interfaces in three‐layer superstructures [(Co40Fe40B20)34(SiO2)66/ZnO/C]46 by means of X‐ray diffraction and X‐ray reflectivity. The samples with different thicknesses of metal‐containing composite layers together with zinc oxide and carbon interlayers were deposited on the glass substrate by ion‐beam sputtering of three targets, one of which was a composite (Co40Fe40B20)34(SiO2)66. X‐ray diffraction results showed the X‐ray amorphous state of the ferromagnetic metal clusters CoFeB, the dielectric matrix of silicon oxide SiO2, and carbon interlayers. However, the intermediate layers of the zinc oxide ZnO were found to have a nanocrystalline structure. The X‐ray reflectivity measurements indicate a good agreement between the experimental and nominal values of both the periods of three‐layer superstructures and the thicknesses of metal‐containing composite layers and interlayers.

In order to break through the conductive percolation threshold limitation of the conventional granular films to increase resistivity (ρ), while keeping large complex permeability (μ̃), a series of compositionally graded FeCoB-SiO2 granular films with different multilayer structures were deposited on flexible substrates. The high-frequency electromagnetic properties were investigated. The experimental results showed that the compositionally graded granular films had obvious in-plane uniaxial magnetic anisotropy and the coercivity in the easy axis (Hce) was as low as 3.97 Oe. Both the ρ (∼15.4 mΩ·cm) and μ̃ (μi'=276.3 and μ″max=441.4) of the compositionally graded FeCoB-SiO2 granular films were simultaneously higher than those of the conventional FeCoB-SiO2 granular films. Two resonance peaks of complex permeability spectrum were also observed.
