Interlayer Exchange Coupling in (Ga,Mn)As-based Superlattices

The interlayer coupling between (Ga,Mn)As ferromagnetic layers in all-semiconductor superlattices is studied theoretically within a tight-binding model, which takes into account the crystal, band and magnetic structure of the constituent superlattice components. It is shown that the mechanism originally introduced to describe the spin correlations in antiferromagnetic EuTe/PbTe superlattices, explains the experimental results observed in ferromagnetic semiconductor structures, i.e., both the antiferromagnetic coupling between ferromagnetic layers in IV-VI (EuS/PbS and EuS/YbSe) superlattices as well as the ferromagnetic interlayer coupling in III-V ((Ga,Mn)As/GaAs) multilayer structures. The model allows also to predict (Ga,Mn)As-based structures, in which an antiferromagnetic interlayer coupling could be expected.Comment: 4 pages, 3 figure

Disturbance of the muscoloskeletal system in juvenile ankylosing spondylitis and disease developed in the adulthood (involvement of spine and sacroiliac joints).

Background. Two forms of ankylosing spondylitis (AS) are distinguished: juvenile and adult, depending on debut age of the disease. The diagnosis of juvenile AS (JAS) is one of the most urgent problems in a pediatric rheumatology. The peculiarities of AS course that onsets in childhood and adulthood are manifested by differences in the nature of a spinal column disturbance. At the same time, the evolution of JAS in adulthood remains unexplored. The goals and objectives of research: to study clinical and X-ray symptoms of spondylopathy and sacroiliitis course, to assess their characteristics in the disease that onset in childhood and adulthood. Material and methods. 217 patients with AS (193 men and 24 women) with an average age of 38 years were examined. The fast-progressing course of the disease was detected in 21% of cases, moderate and high degree of activity – in 79% of cases, the ІІ-ІІІ stage in 82%, and polyarthritis – in 65%. JAS was detected in 16% of cases (all boys), among them the third stage occurred twice more likely than among the other patients. Results. The clinical and radiologic signs of spondylopathy and sacroiliitis are observed in 95% and 97% of the total number of AS cases, respectively, among all patients with JAS lumbago was detected 4,3 times more frequently, sciatic muscles hypotrophy – 7,8 times, "the string symptom" - 2,9 times", the calcification of the spinal cord - 2,3 times, whereas the prevalence of spinal column injury, the severity of cervico-spondylopathy and sacroiliitis among patients with the disease debut in the adulthood is significantly greater, and the involvement in the process of the lumbar and thoracic spine are detected correspondingly twice as often and by 19%, occurrence of dorsalgia is 4 times as often, the limitation of body lateral bendover by 59%, while there are ambiguous dispersion-correlation links with extraarticular (systemic) manifestations of the disease, and the high prevalence of a peripheral articular syndrome regarding spondylopathy in JAS is a negative prognosis sign, and for the remaining patients there are indices of the Lansbury index and the index of arthro­pathy progression. Conclusion: the onset of AS in adulthood is a risk factor for the severe course of spondylopathy

Thermally activated decomposition of (Ga,Mn)As thin layer at medium temperature post growth annealing

The redistribution of Mn atoms in Ga1-xMnxAs layer during medium-temperature annealing, 250-450 oC, by Mn K-edge X-ray absorption fine structure (XAFS) recorded at ALBA facility, was studied. For this purpose Ga1-xMnxAs thin layer with x=0.01 was grown on AlAs buffer layer deposited on GaAs(100) substrate by molecular beam epitaxy (MBE) followed by annealing. The examined layer was detached from the substrate using a “lift-off” procedure in order to eliminate elastic scattering in XAFS spectra. Fourier transform analysis of experimentally obtained EXAFS spectra allowed to propose a model which describes a redistribution/diffusion of Mn atoms in the host matrix. Theoretical XANES spectra, simulated using multiple scattering formalism (FEFF code) with the support of density functional theory (WIEN2k code), qualitatively describe the features observed in the experimental fine structure

Применение импульсного тока для растворения жаропрочного сплава ЖС32-ВИ

Objectives. To identify the regularities of electrochemical processing of the heat-resistant GS32-VI alloy in a sulfuric acid electrolyte with a concentration of 100 g/dm3 under the action of a pulsed current in a pulsed mode.Methods. Using the electrochemical technological complex EHK-1012 (developed by IP Tetran) and a non-compensatory method of measuring potential, polarization and depolarization curves with a change in pulse duration and a pause between them were recorded. The current pulses had an amplitude ranging from 0 to 3.5 A (when recording the polarization and depolarization curves), pulse durations ranging from 200 to 1200 ms, and a pause (delay) between pulses ranging from 50 to 500 ms. There were no reverse current pulses.Results. The parameters of the current program that provide the maximum values of the alloy dissolution rate and current output were determined: with a current pulse amplitude of 2 A, a current pulse duration of 500 ms, and a pause duration between pulses of 250 ms, the maximum dissolution rate of the alloy is 0.048 g/h·cm2, while the current output for nickel is 61.6% with an anode area of 10 cm2. The basic technological scheme for processing the heat-resistant GS32-VI alloy, which includes anodic alloy dissolution in a pulsed mode, is proposed.Conclusions. Electrochemical dissolution of GS32-VI alloy under pulsed current action results in an optimal dissolution rate ratio of the alloy components, ensuring the production of a cathode precipitate with a total nickel and cobalt content of 97.5%.Цели.

Амплитуда импульсов тока находилась в диапазоне значений от 0 до 3.5 А (при снятии поляризационных и деполяризационных кривых), длительности импульсов изменялись от 200 до 1200 мс, пауза (задержка) между импульсами – от 50 до 500 мс, импульсы реверсивного тока отсутствовали.Результаты. Определены параметры токовой программы, обеспечивающие максимальные значения скорости растворения сплава и выхода по току. При амплитуде импульса тока 2 А, длительности импульса тока 500 мс и продолжительности паузы между импульсами 250 мс максимальная скорость растворения сплава 0.048 г/ч·см2, при этом выход по току для никеля равен 61.6% при площади анода 10 см2. Предложена принципиальная технологическая схема переработки жаропрочного сплава ЖС32-ВИ, включающая анодное растворение сплава в импульсном режиме.Выводы. Электрохимическое растворение сплава ЖС32-ВИ под действием импульсного тока способствует оптимальному соотношению скоростей растворения составляющих сплава, что обеспечивает получение катодного осадка с суммарным содержанием никеля и кобальта 97.5%
