(La0.4Eu0.6)0.7Pb0.3MnO3 single crystal: magnetic and transport properties; electron magnetic resonance measurements / K. G. Patrin [et al.] // Workshop INTAS - Sib. Branch of the RAS Sci. Cooperation on the Res. Project “New Layered 3d-Materials for Spintronics” / chairman G. A. Petrakovskii. - 2007. - P. 15
Аннотация: INTAS (The International Association for the Promotion of Cooperation with Scientists from the New Independent States of the Former Soviet Union) — международная ассоциация по содействию сотрудничеству с учёными новых независимых государств бывшего Советского Союза. Некоммерческая организация, финансировалась главным образом из бюджета Европейского Союза. Являлась крупнейшим фондом, поддерживающим научное сотрудничество между учёными стран бывшего СССР и Европейского Союза с 1993 г. Программы INTAS охватывали широкий круг научно-исследовательских проблем. 22 сентября 2006 года было принято решение о прекращении осуществления программы на основании рекомендации Европейской Комиссии. С 1 апреля 2007 года прекратилось распределение новых грантов.

Аннотация: The discovery of a novel effect in the transport through a QD spin-dependently coupled to magnetic contacts is reported. For a finite range of source-drain voltages the spin projections of the current cancel exactly, resulting in a completely suppressed output current. The spin down current behaves as one normally expects whereas the spin up current becomes negative. As the source-drain voltage is increased the spin up current eventually becomes positive. Thus, tuning the source-drain voltage such that the spin up current vanishes will result in a perfect spin filter.

Doped Mott-Hubbard materials -- Metal-insulator transition -- First removal -- electron states
Аннотация: A simple metal-insulator criterion for doped Mott-Hubbard materials has been derived, Its readings are closely related to the orbital and spin nature of the ground states of the unit cell. The available criterion readings (metal or insulator) in the paramagnetic phase reveal the possibility of the insulator state of doped materials with the forbidden first removal electron states. According to its physical meaning, the result is similar to the Wilson's criterion in itinerant electron systems. The application of the criterion to high-T-c cuprates is discussed.

Аннотация: First-principles calculations of the physical properties of ionic crystals are reviewed. Two markedly different approaches within the framework of the density functional theory are described. In one of them, the electron spectrum and wave functions are treated within the standard band picture based on the solution of Kohn-Sham equations. In the second approach, the total electron density of a crystal is represented as a super-position of the densities of individual ions. The problem of determining the electric polarization of a crystal is discussed for each approach. It is shown that it is the use of Bloch functions rather than the physics of the phenomenon that complicates the solution of this problem within the Kohn-Sham framework. The deformable and polarizable ion model is described in detail, and its application to calculating many properties of ionic crystals, including the lattice dynamics and structural stability of crystal phases, is discussed.

    Analysis of Ehrlich ascites carcinoma with electron paramagnetic resonance / N. V. Latyshev, O. V. Kryukova, V. F. Pyankov, S. V. Stolyar // IEEE Ural-Siberian conference on computational technologies in cognitive science, genomics and biomedicine (CSGB). - 2021. - Ст. 9496012. - P. 290-293DOI 10.1109/CSGB53040.2021.9496012. - Cited References: 10
   Перевод заглавия: Анализ асцитной карциномы Эрлиха с помощью электронного парамагнитного резонанса
Аннотация: The study was aimed to reveal the dependence of changes in the content of metal-containing proteins and freeradical forms in a suspension of the experimental tumor in different periods of tumor growth using electron paramagnetic resonance. The object of the study was Ehrlich's ascites carcinoma, an experimental undifferentiated tumor, which is used to study various aspects of tumor development under external influences. Ehrlich ascites carcinoma was inoculated into the peritoneal cavity of laboratory mice. We believe that the determination of the concentrations of metal-containing proteins and free-radical forms using this method may be an important prognostic parameter for assessing the state of the tumor. Changes in metabolism will inevitably affect the functionality of cells and, as a consequence, the dynamics of tumor growth. The results of the study showed that metalcontaining proteins belonging to ascites plasma, such as transferrin, ferritin and ceruloplasmin, do not undergo significant changes. The signal from molybdenum-containing proteins also does not change at the stages of experimental tumor growth under consideration. However, in the course of this experiment, it was possible to record a slight decrease in the intensity of the formation of denitrosyl iron complexes with the development of a tumor in the body.

Аннотация: A many-electron model of the energy band structure of VBO3 and of Fe1 - xVxBO3 solid solutions is proposed with strong electron correlations taken into account. Experimental optical absorption spectra and data on the resistivity are discussed in the framework of the suggested model. Variation in the magnetic and electronic properties of VBO3 and Fe1 - xVxBO3 under high pressure is predicted. For VBO3, a Mott-Hubbard (insulator-metal) transition is expected in the high-pressure phase. In Fe1 - xVxBO3 solid solutions, a nontrivial variation in the properties is predicted, leading to the appearance of a different magnetic state. (C) 2004 MAIK "Nauka / Interperiodica".

PMMA opal -- Photonic crystal -- Electron microscopy -- Angular resolved reflective spectroscopy
Аннотация: PMMA opal crystal was prepared by a simple hybrid method, which includes sedimentation, meniscus formation and evaporation. We investigated three surfaces of this crystal by angle-resolved reflective light spectroscopy and SEM study. The angle-resolved reflective measurements were carried out in the 400–1100 nm range. We have determined the high-quality ordered surface of the crystal region. Narrow particle size distribution of the surface has been revealed. The average particle diameter obtained with SEM was nearly 361 nm. The most interesting result was that reflectivity of the surface turned out up to 98% at normal light incidence. Using a fit of dependences of the maximum reflectivity wavelength from an angle based on the Bragg–Snell law, the wavelength of maximum 0° reflectivity, the particle diameter and the fill factor have been determined. For the best surface maximum reflectivity wavelength of a 0° angle was estimated to be 869 nm. The particle diameter and fill factor were calculated as 372 nm and 0.8715, respectively. The diameter obtained by fitting is in excellent agreement with the particle diameter obtained with SEM. The reflectivity maximum is assumed to increase significantly when increasing the fill factor. We believe that using our simple approach to manufacture PMMA opal crystals will significantly increase the fabrication of high-quality photonic crystal templates and thin films

Аннотация: The structural and magnetic properties of a niobium nitride (NbN) film prepared by reactive sputtering onto a quartz substrate are investigated. It is shown using scanning electron microscopy that the film has a columnar structure with a diameter of crystallite columns of about 50 nm. The film magnetization loops are measured for the field orientation parallel and perpendicular to its surface. Based on the experimental data, the critical current densities of the film are estimated in both cases. For the field parallel to the film surface, the estimate is 6.5 × 104 A/cm2 at the liquid helium temperature. For the field perpendicular to the surface, the critical current density is close to the depairing current density (107 A/cm2). Analysis of the results based on different models of magnetic vortex pinning in superconductors shows that in the former case, pinning occurs at the boundaries of columns in the bulk of the sample, while in the latter case, it is determined by the influence of the surface barrier.

Аннотация: We search for anomalous normal and superconductive behavior in the two-band Hubbard model with one narrow band. We analyze the influence of the electron–polaron effect and the Altshuler–Aronov effect on effective mass enhancement and scattering times of heavy and light components in the clean case. We find anomalous behavior of resistivity at high temperatures T>W∗hT > W_{h}^{*} both in 3D and 2D situations. The SC instability in the model is governed by an enhanced Kohn–Luttinger effect for p-wave pairing of heavy electrons via polarization of light electrons.

Аннотация: We discuss the mechanisms of unconventional superconductivity and superfluidity in 3D and 2D fermionic systems with purely repulsive interaction at low densities. We construct phase diagrams of these systems and find the areas of the superconducting state in free space, as well as on the lattice in the framework of the Fermi-gas model with hard-core repulsion, the Hubbard model, the Shubin-Vonsovsky model, and the t-J model. We demonstrate that the critical superconducting temperature can be greatly increased in the spin-polarized case or in a two-band situation already at low densities. The proposed theory is based on the Kohn-Luttinger mechanism or its generalizations and explains or predicts anomalous p-, d-, and f-wave pairing in various materials, such as high-temperature superconductors, the idealized monolayer and bilayer of doped graphene, heavy-fermion systems, layered organic superconductors, superfluid 3He, spin-polarized 3He mixtures in 4He, ultracold quantum gases in magnetic traps, and optical lattices.

Аннотация: The spin dynamics, magnetic structures and magnetic anisotropy of single crystals PrxY1−xFe3(BO3)4 have been studied using antiferromagnetic resonance (AFMR) in a wide range of frequencies, magnetic fields, and temperatures. The frequency-field dependences of AFMR for the crystals with x = 0.25 and 0.45 are characteristic of antiferromagnets with the easy plane (EP) anisotropy. The crystals with x = 0.75 and 1.0 exhibit frequency-field dependences that are typical for antiferromagnets with the easy axis (EA) anisotropy. In these crystals, a significant decrease in the effective anisotropy fields of praseodymium upon the transition to the spin-flop state has been found. It is shown that this is the main reason for the large lability intervals, within which the regions of coexistence of the collinear and spin-flop states overlap. In the crystal with x = 0.67, the magnetic field applied along the trigonal axis of the crystal leads to the spin reorientation transition from the EA to the EP state. A magnetic phase diagram of the states on the plane "magnetic field - temperature" is built. In this crystal, the effective anisotropy field of praseodymium also decreases upon the transition to the field-induced EP state. Diamagnetic dilution of the praseodymium subsystem leads to the contribution of this subsystem to the total anisotropy field depending almost linearly on the praseodymium concentration.

Аннотация: A novel hybrid scheme is proposed and applied for band structure calculations of undoped n-type cuprate Nd2CuO4. The ab initio LDA calculation is used to obtain single electron and Coulomb parameters of the multiband Hubbard-type model. In strong correlation regime the electronic structure within this model is calculated by the generalized tight-binding (GTB) method, that combines the exact diagonalization of the model Hamiltonian for a small cluster with perturbation treatment of the intercluster hopping and interactions. For Nd2CuO4, this scheme results in charge transfer insulator with value of the gap and band dispersion in agreement to the experimental data. (c) 2006 Elsevier B.V. All rights reserved.

band calculations -- Hubbard model -- f-electrons
Аннотация: We show that in order to properly describe the bonding properties of strongly correlated systems, here demonstrated for praseodymium metal, it is necessary to split the f-electron system into two parts. Using perturbation theory from the atomic limit we show that LDA-based calculations with f-electrons in the core can be considered as the limit of an infinite Hubbard U. Then, the correction to the total energy proportional to 1/U makes the upper f(2)-->f(3) intra-atomic transitions (IT) important. Mixing interaction and f-f-hopping delocalize these IT and some of them become populated. These IT give an additional contribution to the cohesive energy. This gain in energy is the reason for the separation of the f-electron system into localized (with reduced spectral weight) and delocalized ones. (C) 1999 Elsevier Science B.V. All rights reserved.

Аннотация: The paper presents the results of the formation and study of the morphological and structural characteristics of the mesoporous ZnO / Al2O3 nanofibers film (ZANF). The deposition of a ZnO layer on Al2O3 nanofibers film (ANF) ~ 1 µm thick was carried out by the method of atomic layer deposition. The morphology of the mesoporous composite layer ZnO / Al2O3 (ZANF) has been studied by scanning and transmission electron microscopy. It is shown that in the process of atomic layer deposition, the ZnO layer grows according to the Stranski-Krastanov mechanism. A ZnO layer less than 5 nm thick gives an island structure in which Al2O3 nanofibers are uniformly coated with ZnO particles, an increase in the ZnO layer thickness to 15 nm demonstrates a continuous coating of Al2O3 nanofibers. The system has a core-shell structure. The resulting composite structures are promising for applications in photocatalysis and gas sensing.
