Аннотация: The structural and magnetic properties of (Fe/Si) N nanostructures obtained by successive deposition on the SiO2/Si(100) surface at a temperature of the substrate of 300 K have been studied. The thicknesses of all Fe and Si layers have been determined by transmission electron microscopy measurements. The magnetic properties have been studied by the X-ray magnetic circular dichroism (XMCD) method near the Fe L 3, 2 absorption edges. The orbital (m l ) and spin (m S ) contributions to the total magnetic moment of iron have been separated. The thicknesses of magnetic and nonmagnetic iron silicide on the Si/Fe and Fe/Si interfaces have been determined with the surface sensitivity of the XMCD method and the model of the interface between the nonmagnetic and weakened magnetic phases.

Аннотация: This paper reports on a study of multilayer Co/Cu films with an effective thickness of the Co layer of similar to 3.5 , which were prepared by magnetron sputtering. The samples prepared have been found to have a metastable multiphase structure. An analysis of the data obtained by structural and, primarily, by magnetic methods has revealed that the main phases are the Co/Cu supersaturated solid solution (alloy) with a Co concentration of about 30 at %, the superparamagnetic phase, and the paramagnetic phase, which is accounted for by the presence of small (a few atoms at most) Co clusters embedded in the Cu matrix. A clearly pronounced maximum in the temperature dependences of the low-field magnetoresistance has been found, which is associated with the temperature of the magnetic phase transition of the supersaturated Co-Cu alloy.

Аннотация: The single crystals Cu1 xNixB2O4 with x ¼ 0:002; 0.005; 0.009; 0.014 were grown by spontaneous crystallization and the magnetic properties of these crystals have been studied. The strong influence of substitution on the value of critical fields H?c at which the modulated states transform into a weak ferromagnetic one was observed in the temperature range 9.5–20 K. The essential change of temperature dependence of a paramagnetic susceptibility w for Ni-doped samples in comparison with pure CuB2O4 was revealed. The modulated state was not observed in the temperature range 9.5–20 K for Ni content more than x ¼ 0:009.

Аннотация: This paper reports on the results of investigations into the temperature and spectral dependences of the magnetic circular dichroism in Dy1-xNix-Ni bilayer films prepared through thermal sputter deposition of components under ultrahigh vacuum. The distribution of the components over the layer thickness is examined by Auger spectroscopy. The nickel content x in Dy1-xNix layers varies from 0.005 to 0.06. It is shown that, in the temperature range 80-300 K, the contribution made to the magnetic circular dichroism by a Dy1-xNix layer in a bilayer film with a nickel content higher than the threshold value is approximately equal to the magnetic circular dichroism observed in an isolated Dy1-xNix film at temperatures below the temperature of the phase transition to a ferromagnetic state (similar to100 K). This phenomenon is explained by magnetic ordering in theDy(1-x)Ni(x) layer of the bilayer film due to the combined effect of two factors, namely, the incorporation of nickel into a dysprosium layer and the presence of a continuous nickel sublayer in the film.

Аннотация: The Faraday effect (FE) was studied in Co-Sm-O composite films consisting of nanoparticles of metallic cobalt embedded in a samarium oxide dielectric matrix. The volume of the magnetic phase was similar to 60%. The FE spectral dependence for the condensates studied revealed a substantial change as compared to that for bulk cobalt samples, as well as for the films of nanocrystalline Co and CoSm films prepared in this study. An enhancement of the FE was also observed in the short-wavelength part of the optical spectrum. (c) 2005 Pleiades Publishing, Inc.

Аннотация: The crystal structure of Tb(30)Fe(70) and Co(50)Pd(50) nanocrystalline films with strong magnetic anisotropy perpendicular to the film plane (K(perpendicular to) similar to 10(6) erg/cm(3)) is investigated using electron diffraction and transmission electron microscopy. All the studied films in the initial nanocrystalline phase undergo an explosive crystallization with the formation of dendrite structures. It is demonstrated that, after crystallization, the Tb-Fe and Co-Pd films exhibit a tetrahedrally close-packed atomic structure that has no analogs among these materials in the equilibrium state. The internal stresses in the films under investigation are estimated from an analysis of the bend extinction contours in the electron microscope images. The inference is made that strong perpendicular magnetic anisotropy can be associated with magnetostriction anisotropy due to the specific features of the film structure.

Аннотация: ZnO and Co-doped ZnO films were synthesized by the radio frequency magnetron sputtering in mixed atmosphere of Ar + 20% O2 and Ar + 20–50% H2. The morphology, chemical composition, crystal structure, optical transmission, electrical resistance, and magnetic circular dichroism of the films were investigated. It was established that the films thickness decreased several times when Ar was partly replaced by hydrogen in the sputtering chamber. At the same time, for the Co-doped ZnO films, the increase in the relative Co content with the increasing hydrogen concentration was observed. These phenomena are explained by the formation of gaseous ZnH2 because of the hydrogen reaction with the growing films under the conditions of the high substrate temperature (450 °C) and, respectively, the decrease in the Zn component in the films. The hydrogenated Co-doped ZnO films exhibit an increase in electric conductivity and ferromagnetic behavior at room temperature. The magnetic nature of the films is explained by a combination of the intrinsic ferromagnetism (due to the formation of the Co-H-Co complex) with the inclusion of metallic Co clusters.

Заглавие : In situ investigations of magneto-optical properties of thin Fe layers
Место публикации : Tech. Phys. - 2013. - Vol. 58, Is. 10. - P.1529-1532. - ISSN 1063-7842, DOI 10.1134/S1063784213100162
Аннотация: A thin polycrystalline Fe film on a single-crystal Si substrate with natural SiO2 oxide is obtained by thermal evaporation in ultrahigh vacuum. The magneto-optical properties of the resultant structure are investigated in situ by the methods of spectral ellipsometry. The values of the coercive force for the Fe film are obtained, and the magnetization reversal loop and the energy dependence of the equatorial Kerr effect are constructed. The effectiveness of magnetoellipsometry for in situ analysis of the geometrical and magnetooptical properties of thin ferromagnetic layers is demonstrated. В© 2013 Pleiades Publishing, Ltd.

Аннотация: Magnetic and magneto-optical properties of the Ni-Ge bilayer films are studied. The unusual temperature behavior of the magnetization curves is revealed: the hysteresis loops at room temperature have a near-rectangular shape; when the films are cooled down to 4.2 K, the coercive force increases by more than an order of magnitude and the asymmetry and displacement of the loop along the field axis are observed. These effects are stronger in thinner Ni layers. The observed features are attributed to the effect of the interlayer between the Ni and Ge layers, which has a complex magnetic structure.

Аннотация: The results of the experimental investigations of the solid-state reaction of Cu with beta brass, which is associated with the Kirkendall, in Cu/beta-CuZn and Cu/Fe/beta-CuZn film systems are reported. It has been shown that the initiation temperature of the solid-state synthesis of alpha brass at the Cu/beta-CuZn interface is about 200A degrees C. The chemically inert Fe barrier layers 420 and 850 nm in thickness between the Cu and beta-CuZn films do not suppress the solid-state synthesis of the alpha brass, but increase the initiation temperature to about 250A degrees C. This behavior indicates that the chemical interaction between the Cu and Zn atoms through the chemically inert Fe layer is long-range. The X-ray photoelectron investigations reveal the migration of Zn atoms from the beta-CuZn layer through the Fe barrier to the Cu layer. The results are interpreted under the assumption that the migration of Zn atoms in the Kirkendall is initiated by the strong chemical interaction between the Cu and Zn atoms in the Cu and beta-CuZn layers, which is due to the synthesis of alpha brass, rather than by the diffusion random walk, as is commonly accepted at present.

Аннотация: The X-ray diffraction, magnetization and electrical conductivity measurements for Gd(0.9)A(0.1)CoO(3-delta) (A = Ba, Sr) have been made. The complicated magnetic behavior, including the paramagnetic-ferromagnetic-antiferromagnetic and paramagnetic-ferromagnetic transitions, was found for Ba- and Sr-doped samples. The gradual insulator-metal transitions were observed in a wide temperature range T = 600-800 K. The complex magnetic and transport data could be explained on the basis of the structural phase separation. (C) 2009 Elsevier B.V. All rights reserved.

Аннотация: In this work the results of investigations of the magneto-optical properties of Co-Ti-O nanogranular films obtained under conditions of the solid-state reaction with the oxygen exchange reaction in the CoO/Ti layered structures are presented. The formation of the granular films with composition in the area of and below a percolation threshold is shown. The magnetooptical spectra features of the obtained films with the filling factor of magnetic phase from 0.3 to 0.52 in comparison with spectra of uniform metallic films are found.В работе представлены результаты исследования структурных и магнитооптических свойств наногранулированных пленок Co-Ti-O, полученных в условиях твердотельной реакции с обменом кислородом в слоистых структурах CoO/Ti. Показано образование гранулированных пленок составов в области и ниже порога перколяции. Обнаружены особенности магнитооптических спектров пленок с коэффициентом заполнения магнитной фазы от 0.3 до 0.51 в сравнении со спектрами сплошных пленок металлов.
