Аннотация: Исследованы магнитные и магнитооптические свойства, а также морфология поверхности и структура поликристаллических пленок La0.7Sr0.3MnO3 различной толщины. Показано, что поверхность пленок шероховатая с характерным линейным размером в плоскости ∼ 30 nm, кристаллиты c линейными размерами 10−20 nm случайно ориентированы в плоскости. Температурные и полевые зависимости намагниченности пленок свидетельствуют об их магнитной неоднородности. В спектрах магнитного кругового дихроизма наблюдается ряд полос, одна из которых при 2.4 eV объясняется вкладом электронов проводимости.

Аннотация: The fractal dimension of the boundaries of clusters formed by pores and granules in polycrystalline materials is shown to be determined by the sample density and crystallite sizes. The dependence of the fractal dimension on the density has a maximum. It is shown that the maximum diamagnetic response can be obtained in a porous high-temperature superconductor with a porosity of 50-60% and small crystallite sizes.

Аннотация: The magnetic and magneto-optical properties as well as the surface morphology and structure of La0.7Sr0.3MnO3 polycrystalline films of different thicknesses have been investigated. It has been shown that films have a rough surface with a characteristic in-plane linear dimension of similar to 30 nm, and crystallites with linear dimensions of 10-20 nm are randomly oriented in the plane. The temperature and field dependences of the magnetization of the films indicate their magnetic inhomogeneity. The magnetic circular dichroism spectra contain a number of bands, one of which at 2.4 eV is explained by the contribution of conduction electrons.

Ba0.6K0.4BiO3 single crystal as a multiple Josephson system: New coherent effect?

Аннотация: The existence of space inhomogeneous superconductor insulator state (SISIS) found out earlier in polycrystalline samples of high-Tc system Ba0.6K0.4BiO3 (Tc?30 K) is confirmed on Ba0.6K0.4BiO3 single crystal. At T* (T*<Tc, T*?17 K) the transition from the homogeneous superconducting state into the SISIS occurs. SISIS is characterized by the appearance of two gapes on the Fermi surface: semi- and superconducting, that are modulated in space in antiphase, the electric transport between superconducting regions being carried out due to Josephson tunneling. Thus the whole sample becomes a multiple Josephson system. Nonlinear I-V curves, depended on temperature and magnetic field, that are typical to a Josephson system, are observed on Ba0.6K0.4BiO3 single crystal at temperatures below T*. Besides, a step like peculiarity at the values of voltage of the order of one and two superconducting gaps shows up. These peculiarities are suppressed by magnetic field much earlier then critical current. Perhaps the last phenomenon is the consequence of "coherent" state of several successive Josephson junctions, appeared in the exfoliation state. В© Published under licence by IOP Publishing Ltd.

Аннотация: Features of the formation of chemically deposited polycrystalline Co-P films with nanometer thicknesses are established by magnetic measurements and analysis of film surface morphology. It is found that the specific value of the magnetooptical Faraday effect in Co-P films exceeds that in Co films by a factor of more than two. This is attributed to the magnetic polarization of a Pd underlayer. It is shown the Kerr effect in Co films is negligibly influenced by the embedding of phosphorus. © 2012 Allerton Press, Inc.

Аннотация: This paper reports on the first study of the magnetic properties of polycrystalline films of CoCr2O4 and CoFe0.5Cr1.5O4 multiferroics. The study covered, in particular, magnetization reversal curves and temperature dependences of the magnetization at temperatures ranging from 4.2 to 300 K in magnetic fields of up to 10 kOe. It has been shown that the Curie temperature and the pattern of the temperature dependence of the magnetization depend on the cation composition of the multiferroic. The temperature dependence of the magnetization of polycrystalline CoCr2O4 films has revealed an anomaly in the temperature range 10-70 K.

Аннотация: Many applications and environmental impact of silver-bearing nanomaterials critically depend upon their specific reactivity, which is still poorly understood. Here, silver nanoparticles (Ag NPs) of about 3-5 nm and 10-12 nm in diameter, uncapped and capped with l-glucose or citrate, were prepared, characterized using UV-vis absorption spectroscopy, SAXS, TEM, and their (electro) chemical oxidation was examined in comparison with each other and bulk metal applying scanning tunneling microscopy and spectroscopy, cyclic voltammetry, and XPS. A resistive switching effect was found in the tunneling spectra measured in air at the smaller uncapped Ag NPs deposited on HOPG and was interpreted in terms of Ag transfer between the particle and the probe. The anodic oxidation of these Ag NPs in 1 M NaOH yielded 3D Ag2O, while only a layer of "primary"Ag(I) oxide emerged on larger uncapped nanoparticles during the potential sweep. The formation of AgO at higher potentials proceeded readily at the "primary"oxide but was retarded at the smaller NPs. The citrate- and glucose-capping substantially impeded the formation both of Ag2O and AgO. The findings highlighted, particularly, a non-trivial effect of particle size and transient mobilization of Ag species on the reactions of silver nanoparticles. (c) 2014 Elsevier B.V.

In particular, magnetization curves and temperature dependences of the magnetic moment of the samples were measured in the temperature range 4.2-300 K in fields of up to 10 kOe. It was shown that the Curie point of a multiferroic depends on its cation composition. It was found that an exchange bias of the hysteresis loop exists in films of the Cr2O3/CoFe2O4 composite multiferroic at temperatures below the N,el point of Cr2O3 (330 K).

Magnetoresistance of porous polycrystalline HTSC: Effect of the transport current on magnetic flux compression in intergranular medium
/ D. A. Balaev [et al.] // Phys. Solid State. - 2014. - Vol. 56, Is. 8. - P. 1542-1547, DOI 10.1134/S1063783414080034. - Cited References: 47

Аннотация: The hysteretic dependences of the magnetoresistance of porous (38% of the theoretical density) granular high-temperature superconductor (HTSC) Bi1.8Pb0.3Sr1.9Ca2Cu3O (x) have been analyzed in the model of the effective intergranular field. This effective field has been defined by the superposition of the external field and the field induced by magnetic moments of superconducting grains. The magnetic flux compression in an intergranular medium, characterized by the effective field, controls the hysteretic behavior of the magnetoresistance. It has been found that the magnetoresistance hysteresis width for the studied porous HTSC depends on the transport current, in contrast to the superconductor of the same composition with high physical density (more than 90% of the theoretical value). For a porous superconductor, a significant current concentration occurs in the region of the grain boundaries, which is caused by features of its microstructure. A current-induced increase in the effective boundary length results in a decrease in the flux compression, a decrease in the effective field in the intergranular medium, and a magnetoresistance hysteresis narrowing with increasing current.

Temperature evolution of the hysteresis in the current-voltage characteristic of a polycrystalline high-temperature superconductor with 1-2-3 structure

Аннотация: The temperature evolution of the current-voltage (I-U) characteristic of a contact of the break-junction type with direct conduction is investigated on a polycrystalline HTSC of the Y-Ba-Cu-O system. The experimental I-U characteristics possessing a hysteresis are correctly described in the framework of the Kummel-Nicolsky theory for an S-N-S contact (S stands for a superconductor; N, for a normal metal) in which the Andreev reflection of quasiparticles from the N-S interface is considered. It is shown that the shape of the I-U curve, as well as the existence of a hysteresis, is determined by the ratio of the number of "long" and "short" intergranular boundaries in the polycrystal under investigation. The coincidence of the calculated and experimental I-U curves made it possible to estimate the effective length of "natural" intergranular boundaries in polycrystalline HTSC materials. The estimate is obtained from the experimental temperature dependence of the critical current in the sample under investigation. (C) 2002 MAIK "Nauka/Interperiodica".

Аннотация: Bulk Y3/4Lu1/4Ba2Cu3O7 + Cu1-xLixO composites with x = 0, 0.003 and 0.06 and varied volume content of Cu1-xLixO have been prepared. Analysis of the transport properties of the composites has shown that they can be represented as a network of superconductor-semiconductor-superconductor (S-Sm-S) weak links. The dependence of the critical current density on the normal resistance for the composites studied shows a behaviour similar to that for single Josephson junctions. The experimental temperature dependences of the critical current are qualitatively described in terms of a theory of S-Sm-S junctions that takes into account the Andreev reflection of carriers from the S-Sm and Sm-S interfaces.

Аннотация: Temperature dependences of transport critical current (Jc) have been studied for polycrystalline HTSC samples of 1-2-3 structure with Y3/4Lu1/4Ba2Cu3O7 composition. The main aim of the investigation was the effect of the boundaries between crystallites on the current-carrying capability of the high-temperature superconductor. The modifications of the boundaries have been achieved by the long time heat treatments up to one week (?150 hours). It has been demonstrated experimentally that the Kulik-Omel'yanchuk theory describes adequately the temperature dependence of Jc of samples with short heat treatment time in "clean" limit. The absolute value of Jc (4.2k) ? 1.4kA/cm2. Long-term heat treated samples have Jc(4.2K) ? 0.1kA/cm2 and the temperature dependence of Jc becomes close to predictions of de Gennes theory. В© 1994.

Difference between the FC and ZFC temperaturecurves has been explained by the presence of the spin glassstate in the samples,and bythe effect of crystallographic anisotropy.With increasing temperaturethehysteresis loopshad demonstrated the increase in a slope, the reduction of a coercive field and the absence of magnetic saturation at high fields. This behavior has been explained by the ordering of the Pr spins and their effect on the total magnetic properties of the films
