“…At the same time, SC layers are chemically homogeneous, and their morphology is determined only by their thickness and roughness. Recently it was shown that the conductive and magnetic properties of MI / SC nanostructures are determined both by the composition and morphology of MI [14] and SC layers [15,16,17]. Some of the recent works were aimed to study an indirect coupling between the nanoparticles in MI layers through semiconducting interlayers.…”

“…The behavior of in-plane electrical resistivity ρ of the multilayered nanostructure in dependence on carbon layer thickness at different temperatures was studied in Ref. [16]. It was shown, that resistivity of the nanostructre decreases by four orders of magnitude with carbon layer thickness h c growth from 0.4 nm to 1.8 nm (Fig.…”

We report on the investigation of morphology, magnetic and conductive properties of the mutilayered nanostructures [(Co 40 Fe 40 B 20 ) 34 (SiO 2 ) 66 ]/[C] 47 consisting of the contacting magnetic (Co 40 Fe 40 B 20 ) 34 (SiO 2 ) 66 nanocomposite and amorphous semiconductor carbon C layers. It is shown by Grazing-Incidence Small-Angle X-ray Scattering method that the ordering and the size of nanoparticles in the magnetic layers do not change profoundly with increasing of carbon layer thickness. Meanwhile, the electrical conductance and the magnetic properties are significantly varied: resistance of the samples changes by four orders of magnitude and superparamagnetic blocking temperature changes from 15 K to 7 K with the increment of carbon layer thickness

“…These systems have found practical application in devices of information storage. It is well known [2] that, in the area of high frequencies, the use of nanostructures becomes more complicated due to the increase of losses caused by eddies currents as the frequency increases, so just the use of nanocomposites at concentrations close to the percolation threshold minimize these losses.…”

Magneto-optics properties of (Co 41 Fe 39 B 20) x (SiO 2) 100−x alloys were studied applying both experimental spectral ellipsometry and quantum mechanical theory (incl. molecular calculus) approaches. Magneto-optics (MO) properties of the alloys were derived from the measured parameters of reflected elliptically polarized light. The experimental data were explained applying selection rules for the magnetic quantum number. Theoretical approach based on electron gas in a metal with angular momentum coupled to magnetic field demonstrated applicability of the magnetic quantum number and Hund's rule for ascertaining the MO alloys properties. In this modeling, the magneto-optics properties of ferromagnetic alloys can be explained being based on derivations for the magnetic quantum number selection rules. Hund's rule directly influences the dielectric tensor off-diagonal elements signs. The nonrelativistic Schrödinger equation for the Co 2 Fe 2 B alloy was numerically solved taking into account spins of Co and Fe atoms as well as orbital moments of wave functions in order to check the theoretical approach. As a result, the MO dispersion curves can be theoretically evaluated using the modified Spicer ratio that includes density of states functions with specific azimuthal and spin quantum numbers.

“…Nanomaterials are so attractive that their production technologies are systematically enhanced. In-depth recognition of ion technologies and more specifically of the ion-beam sputtering [3][4][5][6] or ion implantation [7][8][9] and of magnetron sputtering [10][11][12] as well as of the plasma and hightemperature techniques [13][14][15][16][17] makes it possible to produce multi-component nanomaterial structures. From a big amount of chemical methods for the production of thin films it is the sol-gel method and chemical deposition techniques that meet the greatest scientific interest [18][19][20].…”

The paper established that, the hopping mechanism of the charge exchange for the (FeCoZr) 64.4 (PZT) 35.6 nanocomposite and the additional polarization of tested sample occurs. As frequency increases two frequency areas where capacitance decreases can be observed. Correlation between the conductivity increase and the capacitance decrease has been observed for the both stages of their variability. Voltage resonance phenomenon for the studied material was observed. The zero crossing in the frequency dependence of phase difference transition is accompanied with this phenomenon, which is reflected by a sharp minimum in the capacitance versus frequency characteristics.
