Slow antiferromagnetic dynamics in the low temperature tetragonal phase of La_{2-x}Sr_xCuO_4 as revealed by ESR of Gd spin probes
V. Kataev,B. Rameev,B. Buechner,M. Huecker,R. Borowski
Physics , 1996, DOI: 10.1103/PhysRevB.55.R3394
Abstract: Measuring the ESR of Gd spin probes we have studied the magnetic properties of the copper oxide planes in the low temperature tetragonal (LTT) phase of Eu doped La_{2-x}Sr_xCuO_4. The data give evidence that at particular levels of Sr and Eu doping the frequency of the antiferromagnetic fluctuations in the LTT phase dramatically decreases at low temperatures by almost three orders of magnitude. However, no static magnetic order has been found for T>8K in contrast to the observation by neutron scattering of stripe ordering of spins below 50K in a Nd doped La_{2-x}Sr_xCuO_4 single crystal. To our opinion static order in the Nd doped compound is induced due to the interaction between the Cu spins with the rare earth magnetic moments. Therefore, a really characteristic property of the magnetism in the LTT structural phase may be not static magnetic order at elevated temperatures but rather extremely slow antiferromagnetic dynamics.
Magnetism of the LTT phase of Eu doped La_{2-x}Sr_xCuO_4
M. Huecker,J. Pommer,B. Buechner,V. Kataev,B. Rameev
Physics , 1997, DOI: 10.1007/BF02765736
Abstract: The ESR signal of Gd spin probes (0.5 at %) as well as the static normal state susceptibility of Eu (J(Eu^{3+})=0) doped La_{2-x-y}Sr_xEu_yCuO_4 reveal pronounced changes of the Cu magnetism at the structural transition from the orthorhombic to the low temperature tetragonal phase for all non-superconducting compositions. Both a jumplike decrease of \chi as well as the ESR data show an increase of the in-plane magnetic correlation length in the LTT phase. From the Gd^{3+} ESR linewidth we find that for specific Eu and Sr concentrations in the LTT phase the correlation length increases up to more than 100 lattice constants and the fluctuation frequency of the CuO_2 spin system slows down to 10^{10}- 10^{11}sec^{-1}. However, there is no static order above T ~ 8K in contrast to the LTT phase of Nd doped La_{2-x}Sr_xCuO_4 with pinned stripe correlations.
Six-fold in-plane magnetic anisotropy in Co-implanted ZnO (0001)
Numan Akdogan,Bulat Rameev,Sumeyra Guler,Osman Ozturk,Bekir Aktas,Hartmut Zabel,Rustam Khaibullin,Lenar Tagirov
Physics , 2010, DOI: 10.1063/1.3223583
Abstract: Magnetic anisotropies of Co-implanted ZnO (0001) films grown on single-crystalline Al2O3 (11-20) substrates have been studied by ferromagnetic resonance (FMR) technique for different cobalt implantation doses. The FMR data show that the easy and hard axes have a periodicity of 60 degrees in the film plane, in agreement with the hexagonal structure of the ZnO films. This six-fold in-plane magnetic anisotropy, which is observed for the first time in ZnO-based diluted magnetic semiconductors, is attributed to the substitution of cobalt on Zn sites in the ZnO structure, and a clear indication for long range ferromagnetic ordering between substitutional cobalt ions in the single-crystalline ZnO films.

Abstract: Aim of this paper is to provide valuable insights into the Maltese legal system with a special focus on private law. The assumption is that this legal system is the byproduct of the "mixing" of innovation and tradition, resulting from the interaction of English law and continental law. A major role in the development of the system is played by courts. Some examples (moral damages and pre-contractual liability) are considered which highlight the importance of the function displayed by Maltese judges.

Abstract: At present, the problem who can and who should solve the question concerning the preparationand recurrent training of pilots of Ukrainian civil aviation is not solved. The necessity of updatingof aircraft’s park in aviation branch and aircraft operation, which was ripened 10 years ago,demands a corresponding infrastructure. It is necessary to understand, that the pilots ready toperform the flights on modern aircrafts, will not appear by themselves, therefore the real actions onmodernization of existing system of aircrew and the aviation personnel preparation as a whole arerequired. Main objective of this work is the determination of the basic components concerning thesolving of the problematic questions on preparation of aircrew on modern types of aircrafts. Duringthe problem analysis it was specified that the present development of system of aircrew preparationin Ukraine is not perfect, and does not correspond the ICAO and EU requirements, therefore needsan immediate intervention at the highest State level. Trainings are not complex, as do not containthe elements of selection of aircrew members cooperation. Programs of recurrent training ofaircrew, courses of pilots training flight preparation were not reconsidered for many years Розглянуто проблему п дготовки п лот в цив льно ав ац Уккра ни, яка на сьогодн нев дпов да вимогам ICAO та С.

Abstract: Substantially nonlinear objects function at limitations of arbitrary kind. These limitations are not necessarily convex areas. For such objects the construction of area of the fully the fully-controlled state area is a serious problem. In the article it has been suggested to replace this task the task of the fully-controlled state area estimation from within. The secure estimation method of the fully-controlled state area has been developed for this purpose. Other dynamic system has been used as a tester (measure) of the fully-controlled state area. Construction and estimation of controllability and accessibility area of this dynamic system well methodically validate and deserved researchers confession. The descriptions concordance requirements of this new object with properties of initial object must be executed and provide property of immersion of new object in an initial object. Possibility is thus opened on the the fully-controlled state area of new object to define the the fully-controlled state area of the initial system На основ процедури мерсування м рних об’ кт в у вих дний об’ кт розроблено методгарантованого оц нювання област повн стю керованого стану.On the basis of procedure of immersion of the measuring objects in an initial object the secureestimation method of the fully controlled state area has been developed.На основе процедуры иммерсирования мерных объектов в исходный объект разработанметод гарантированного оценивания области полностью управляемого состояния.

Abstract: The system method of immersion and virtualization of measured systems in real process is offered. The method works out problem of virtual systems formation and sets conditions at which virtual object to become measuring system for of completely controlled condition field. Here the system of interactively oriented rectangular n-dimensional parallelepipeds is used as measuring system. Imbeddedness of measuring system in real process is understood as process of approximation of a real system controlled condition cone by system of rectangular n-dimensional parallelepipeds.

Abstract: Determination of small forms is considered in architecture and in a sculpture. Certainly difference between national and international style in a design. Their use is considered in the design of interiors of passenger spaces of air terminals on existent examples. Connection is analysed between architectural small forms and by the sculpture of small forms, which consists in the transmission of the general semantic and aesthetically beautiful loading on a man, namely to create feeling of comfort, national self-esteem, national pride, and but to consciousness Рассмотрено определение малых форм в архитектуре и скульптуре. Определена разница между национальным и интернациональным стилями в дизайне. Показано их использование в дизайне интерьеров пассажирских пространств аэровокзалов. Проанализирована связь между архитектурой и скульптурой малых форм, заключающаяся в передаче смысловой и эстетической нагрузки на человека, создании ощущения комфорта, национального самоуважения, национальной гордости и самосознания.
