(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
