Заглавие : The phases formed in Sn/Co thin bilayer upon heating
Колич.характеристики :5 с
Место публикации : J. Solid State Chem. - 2024. - Vol. 334. - Ст.124693. - ISSN 00224596 (ISSN), DOI 10.1016/j.jssc.2024.124693. - ISSN 1095726X (eISSN)

Аннотация: The structure and phases formed in Sn/Co thin films are interesting both from the solid-state chemistry point of view and due to applications of such a metallic bilayer. The phases forming in thin films Sn/Co obtained by thermal vacuum evaporation on two different substrates SiO2 and MgO(100) at different annealing temperatures have been studied. Annealing above 110°С results in intermetallics formation in the films. The hcp-cobalt is grown in the films on SiO2 substrate, and the fcc-Co is observed on MgO(100) substrate. It is found that the stable α-Co3Sn2 intermetallic is formed at higher annealing temperature in film on MgO(100) substrate. We show that transformations related to mass transfer in the Sn/Co bilayers were up to 500°С and were finished upon reaching the thermodynamically equilibrium phase composition at this temperature.

Заглавие : Temperature dependence of the backscattering coefficient measured by ALOS PALSAR during cooling and heating of tundra topsoil
Место публикации : Журн. радиоэлектрон. - 2019. - № 11. - ISSN 1684-1719 (eISSN), DOI 10.30898/1684-1719.2019.11.19; J. Radio Electron.

Аннотация: In this paper, dependences of backscattering coefficient on Arctic tundra soil temperature were investigated. The backscattering coefficient was measured by ALOS PALSAR (1.3GHz) over areas near to Imnaviat weather station in the North Slope of Alaska in the period from January 12, 2009 to April 20, 2011. It has been experimentally and theoretically shown that there is a strong correlation relationship no worse than 0.76 between the surface soil temperature measured by weather stations and backscattering coefficient. The variations of the backscattering coefficient was found to be about 5-6 dB over the test site when soil surface temperature changes from -10°С to 10°С. This study contributes to further understanding the processes of scattering of frozen Arctic soils that is pertinent to developing new remote sensing algorithms for the permafrost region.В данной работе представлены результаты исследования температурной зависимости коэффициента обратного радарного рассеяния, измеренного ALOS (PALSAR) на частоте 1,26ГГц, для тундрового тестового участка, расположенного на Северном склоне Аляски вблизи метеорологической станции Имнавиат. Экспериментально и теоретически показано, что температура поверхности почвы, измеренная метеостанцией в период с 12 января 2009 года по 20 апреля 2011 года, и коэффициент обратного рассеяния нелинейно зависят друг от друга с квадратом коэффициента корреляции 0,76. Данная зависимость удовлетворительно может быть описана моделью рассеяния Оха и температурно-зависимой диэлектрической моделью талых и мёрзлых тундровых почв с высоким содержанием органического вещества. Показано, что в диапазоне изменений температуры поверхности почвы от -10°С до 10°С вариации коэффициента обратного рассеяния на испытательном участке не превышают 5-6 дБ. Данное исследование способствует дальнейшему пониманию процессов рассеяния микроволн мерзлыми арктическими почвами, с целью разработки новых алгоритмов дистанционного зондирования Арктических регионов.

Аннотация: Ferrihydrite nanoparticles are synthesized and characterized. The dependences of heating of powders are studied upon pumping by a high-frequency electromagnetic field on a dc magnetic field. It is shown that the experimental dependence of the temperature of particles on a dc magnetic field is consistent with the theory of ferromagnetic resonance for an isotropic superparamagnet.

Аннотация: In this paper, the results of radiothermal and radar remote sensing of several Arctic tundra test sites were investigated to establish the dependences of the reflectivity and backscattering coefficient on soil temperature. The brightness temperature and backscattering coefficient were measured by a SMAP radiometer (1.4GHz) and Sentinel-1 radar (5.4GHz) over areas near to Franklin Bluffs weather station in the North Slope of Alaska and Isachsen weather station on Ellef Ringnes Island respectively. It has been experimentally and theoretically shown that between the surface soil temperature measured by weather stations in the period 2015-2016 and the reflectivity or backscattering coefficient there is a strong correlation relationship no worse than 0.68. In addition, in the range of soil surface temperature changes from -30°C to 0°C, the variations in the backscattering coefficient and reflectivity are about 4 dB for both test sites. This study contributes to further understanding the processes of microwave emission and scattering of frozen Arctic soils that is pertinent to developing new remote sensing algorithms for the permafrost region.

Заглавие : Raman scattering study of the upper phase transition in CsScF4
Место публикации : Journal of Raman Spectroscopy. - 2000. - Vol. 31, Is. 3. - P.151-155. - ISSN 0377-0486, DOI 10.1002/(SICI)1097-4555(200003)31:3151::AID-JRS5103.0.CO;2-T
Ключевые слова (''Своб.индексиров.''): article--crystal--heating--high temperature--melting point--neutron scattering--phase transition--photon--raman spectrometry--temperature dependence
Аннотация: Effects of the phase transition between the high-temperature tetragonal phases of the CsScF4 crystal were studied by Raman scattering. The appearance of new lines including a soft mode was observed below the phase transition point, in complete accordance with the new crystal symmetry. The behavior of the soft mode, which corresponds to in-phase rotations of ScF6 rigid groups around the z-axis (and out-of-phase within perovskite-like layers), resembles that observed earlier in RbAlF4, which suggests a similar mechanism of this transition in both crystals.

The multiple vanishing resonant lines corresponding to optical bound states in the continuum are observed. The abrupt change in the resonant linewidth near the vanishing point can be used for temperature sensing.

Аннотация: Temperature evolution of the current-voltage characteristics (CVCs) of a single-crystal lanthanum manganite (La0.5Eu0.5)(0.7)Pb0.3MnO3 is investigated in a wide (up to 1 A) range of instrumental currents. Effects of a transport current and an applied electric field on the resistance of the material are studied in view of possible implementation of the charge ordering break in dielectric regions occurring due to phase separation in manganites. A negative differential resistance portion observed in the CVCs suggests the presence of a current switching effect. Below the temperature of the metal-dielectric transition in (La0.5Eu0.5)(0.7)Pb0.3MnO3, the hysteresis is observed in the CVC. The detailed analysis of the internal sample heating on the basis of experimental data on thermal conductivity showed, however, that these CVC features can be explained within the concept of non-equilibrium heating of electron gas.

Ключевые слова (''Своб.индексиров.''): laser treatment--nanocarbon materials--technically pure iron--microhardness--microstructure--wear resistance--friction coefficient
Аннотация: The mechanism of the surface reinforcement and wear resistance of steel products are studied as a result of creating the strengthening layers with the nanocarbon using the laser heating. Laser surface treatment using soot remaining after fullerene extraction leads to a more than fivefold increase in the microhardness (up to 1086 HV) and a decrease in the friction coefficient by 20–30%. The conclusion that the reinforcement mechanism involves the formation of eutectic, cementite, martensite, the cellular substructure, and grain refinement is carried out based on metallographic studies of the strengthened layers of technically pure iron with a thickness of 20–70 μm.

Аннотация: Current-voltage characteristics of the polycrystalline substituted lanthanum manganite La0.7Ca0.3MnO3 were experimentally studied at T - 77.4 K in magnetic fields up to 13 kOe. In these characteristics, a portion of negative differential resistivity was observed above a certain threshold value of critical current density j caused, in our opinion, by nonequilibrium heating of the electron gas due to low thermal conductivity of the manganite material. Because of the nonlinearity of the current-voltage characteristics, the field dependences of resistivity rho( H) appear extremely sensitive to the value of a transport current. In this case, the rho( H) dependences reveal both ordinary negative and positive magnetoresistance. (C) 2011 American Institute of Physics. [doi: 10.1063/1.3573666]
