Аннотация: Magnetic properties of GdFe3(BO3)(4) single crystals were investigated by Fe-57-Mossbauer spectroscopy and static magnetic measurements. In the ground state, the GdFe3(BO3)(4) crystal is an easy-axis compensated antiferromagnet, but the easy axis of iron moments does not coincide with the crystal C-3 axis, deviating from it by about 20 degrees. The spontaneous and field-induced spin reorientation effects were observed and studied in detail. The specific directions of iron magnetic moments were determined for different temperatures and applied fields. Large values of the angle between the Fe3+ magnetic moments and the C-3 axis in the easy-axis phase and between Fe3+ moments and the a(2) axis in the easy-plane phase reveal the tilted antiferromagnetic structure.

Аннотация: The method to investigate "single-ion" exchange anisotropy (as predicted by the pair model) is treated by exploration of several isostructural diamagnetic crystals containing magnetic impurities. The electron paramagnetic resonance (EPR) spectra were observed for ferric borate isostructural crystals MBO(3): Fe(3+) (M = Ga, In, Lu, Sc). The experimental dependences of the spin-Hamiltonian axial parameters of the second-order D(S) and fourth-order (a-F)(cS) versus total pair spin S are presented. The contributions arising from the distortion of the parent crystal lattice MBO3 under magnetic dilution are estimated. The microscopic derived expressions for the "single-ion" contribution to the anisotropy are also presented. The present experimental data enable estimation of the "single- ion" exchange contribution for FeBO(3), MnCO(3), and alpha-Fe(2)O(3) crystals at T= 0 K. The quantitative estimations for EPR are in satisfactory agreement among themselves and with the experimental data.

Аннотация: By means of magnetic susceptibility and specific heat measurements, x-ray and unpolarized neutron diffraction investigations on powder and single-crystal samples, simultaneous long-range antiferromagnetic Fe and Nd ordering in NdFe3((BO3)-B-11)(4) with R32 chemical structure has been found at temperatures below T-N = 30.5(5) K down to 1.6 K. At temperatures down to 19 K the propagation vector is k(hex) = [0, 0, 3/2] and becomes slightly incommensurate at lower temperatures. Combined with symmetry analysis, best powder neutron profile fits are obtained with magnetic spiral configurations with the magnetic moments oriented parallel to the hexagonal basal plane according to the irreducible representations tau(3) in the commensurate case. This is in agreement with the easy directions of magnetization perpendicular to the c-axis as determined by magnetic susceptibility measurements. At 1.6 K the magnetic Fe moment amounts to 4.9 mu(B) B close to the free ion moment of Fe3+. The magnetic Nd3+ moment saturates presumably due to crystal-field effects at 2.7 mu(B).

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: Heat capacity measurements were performed for a single crystal wafer of PMN in the temperature range of 170-250 K applying an electric field E = 3.0 kV/cm along the [111] direction. The heat capacity anomalies related to the phase transition at Tc = 210 K upon zero field heating after field cooling and at Tc = 223 K upon field cooling have been found. The results obtained are discussed together with the data of previous studies in the frame of the spherical random bondrandom field model.

Аннотация: Magnetization, susceptibility and neutron scattering measurements were performed on the terbium iron borate TbFe3(BO3)(4). Structural and magnetic phase transitions were obtained as a function of external magnetic field and temperature. A metamagnetic transition of the terbium spins and a spin-flop transition of the iron sublattice are obtained at an external magnetic field 35 kOe < Ht < 60 kOe. The values of the effective exchange HE and the anisotropy HA fields are evaluated. Temperature dependent neutron diffraction studies reveal the magnetic structure of TbFe3(BO3)(4) and the thermal evolution of the two magnetic sublattices. An antiferromagnetic coupling along the helicoidal chains of Fe atoms sets in at 40 K with a propagation vector k = [ 0 0 1/2]. The magnetic ordering of the Tb sublattice sets in at the same temperature and leads to an anti-parallel alignment of the Fe and Tb moments within the a-b-planes with mu(Fe) = 4.4 mu(B) and mu(Tb) = 8.6 mu(B) at 2 K.

Аннотация: We present a detailed study on the magnetic order in the undoped mother compound LaFeAsO of the recently discovered Fe-based superconductor LaFeAsO(1-x)F(x). In particular, we present local probe measurements of the magnetic properties of LaFeAsO by means of (57)Fe Mossbauer spectroscopy and muon-spin relaxation in zero external field along with magnetization and resistivity studies. These experiments prove a commensurate static magnetic order with a strongly reduced ordered moment of 0.25(5)mu(B) at the iron site below T(N)=138 K, well separated from a structural phase transition at T(S)=156 K. The temperature dependence of the sublattice magnetization is determined and compared to theory. Using a four-band spin density wave model both, the size of the order parameter and the quick saturation below T(N) are reproduced.

SEM and XRD data prove a high degree of texture of the bulk samples obtained. Magnetic measurements performed in directions H parallel to c-axis and H parallel to a-b-planes of Bi2223 crystallites demonstrates anisotropy of magnetization confirming the texture of the ceramics. The materials obtained possess large diamagnetic response in the direction H parallel to a-b-planes of Bi2223 crystallites at both 77.4 and 4.2 K.

Аннотация: Evolution of the phase state of paramagnetic additions at various stages of synthesis and subsequent thermal treatment of glasses of the system Al(2)O(3)-K(2)O-B(2)O(3) simultaneously doped with Fe(2)O(3) and MnO is studied by means of a combination of experimental techniques: Faraday rotation (FR), electron magnetic resonance (EMR), transmission electron microscopy (TEM), Mossbauer spectroscopy, and magnetic measurements. Both FR and EMR show that magnetically ordered clusters occur already at the first stage of the glass preparation. In particular, for the ratio of the Fe and Mn oxides in the charge close to 3:2, fine magnetic nanoparticles are formed with characteristics similar to those of manganese ferrite. By computer simulating the EMR spectra at variable temperatures, a superparamagnetic nature of these nanoparticles is confirmed and their mean diameter is estimated as approximately 3.2 nm. In the thermally treated glasses larger magnetic nanoparticles are formed, giving rise to FR spectra, characteristic of magnetically ordered systems, and the EMR spectra different from those in as-prepared glasses but also showing superparamagnetic narrowing. The Mossbauer spectroscopy corroborates the manganese ferrite structure of the nanoparticles and indicates their coexistence in the ferrimagnetic and superparamagnetic states. The TEM shows the presence of polydisperse nanoparticles on the background of the glass matrix, and electron diffraction of a selected region containing larger particles indicates a crystal structure close to that of MnFe(2)O(4). Energy-dispersive atomic x-ray spectra confirm that the major part of Fe and Mn introduced to the glass composition is gathered in the particles, with the concentration ratio close to 2:1, characteristic of bulk MnFe(2)O(4). Magnetic hysteresis loops of samples subjected to an additional thermal treatment demonstrate a strong increase in the coercive force, remnant magnetization, and high-field magnetic susceptibility with temperature decrease. The consistent results obtained using various techniques demonstrate that the formation of nanoparticles with characteristics close to those of MnFe(2)O(4) confers to these glasses magnetic and magneto-optical properties typical of substances possessing magnetic order.

Аннотация: The time evolution of the magnetoresistance of bulk YBCO + CuO composites at T = 4.2 K in constant applied magnetic fields was studied to clarify the mechanism of hysteretic behavior of magnetoresistance R(H) of granular HTSC. The composites represent "model" granular HTSC with weakened Josephson coupling between superconducting (YBCO) crystallites. It was found for the first time that on the ascending branch of R(H) dependence, the resistance at H = const decreased with time while on the descending branch, the resistance increased with time in ail applied constant magnetic field. In the range of low magnetic fields (below the minimum point of the descending branch of the R(H) dependence), the resistance at H const decreased again. Similar measurements performed oil pure polycrystalline YBCO at T = 77.4 K have shown that the behavior of evolution of resistance with time is similar to that observed for the composite. This proves the peculiarity of time evolution of maignetoresistance to be a common feature of granular HTSCs. The behavior revealed is well described by the model Of granular HTSC, where the intergrain media is in an effective magnetic field which is the superposition of the external field and the field induced by superconducting grains. The time evolution of resistance reflects the time relaxation of magnetization of HTSC grains due to the intragrain flux Creep Processes. (C) 2008 Elsevier Ltd. All rights reserved.

Аннотация: This paper reports on a joint theoretical and experimental study of the Pauli quantum-mechanical stress tensor T(alpha beta)(x,y) for open two-dimensional chaotic billiards. In the case of a finite current flow through the system the interior wave function is expressed as psi=u + iv. With the assumption that u and v are Gaussian random fields we derive analytic expressions for the statistical distributions for the quantum stress tensor components T(alpha beta). The Gaussian random field model is tested for a Sinai billiard with two opposite leads by analyzing the scattering wave functions obtained numerically from the corresponding Schrodinger equation. Two-dimensional quantum billiards may be emulated from planar microwave analogs. Hence we report on microwave measurements for an open two-dimensional cavity and how the quantum stress tensor analog is extracted from the recorded electric field. The agreement with the theoretical predictions for the distributions for T(alpha beta)(x,y) is quite satisfactory for small net currents. However, a distinct difference between experiments and theory is observed at higher net flow, which could be explained using a Gaussian random field, where the net current was taken into account by an additional plane wave with a preferential direction and amplitude.

Аннотация: We present measurements of oscillations in the electron density, ion density and ion velocity in the induced magnetosphere of Mars. The fundamental frequency of the oscillations is a few millihertz, but higher harmonics are present in the spectrum. The oscillations are observed in a region where there is a velocity shear in the plasma flow. The fundamental frequency is in agreement with computational results from an ideal-MHD model. An interpretation based on velocity-shear instabilities is described.

We report the temperature- dependent measurements of the strain, thermal expansion coefficient and the magnitude of root mean square polarization. The results obtained are discussed together with the data on the structure and dielectric properties.

Аннотация: We present the results of the magnetic and heat capacity study of a magnetic phase diagram of a HoFe3(BO3)(4) single crystal. Two magnetic phase transitions are found in the low-temperature region. The transition from the paramagnetic to easy-plane antiferromagnetic state occurs at T-N = 37.4 K and is independent of an applied magnetic field. The sharp heat capacity peaks and magnetization jumps corresponding to the spontaneous and field-induced spin-reorientation transitions between the easy-axis and easy-plane states are observed below 4.7 K. Also, the additional heat capacity peaks, which can be attributed to the Schottky anomalies with the field-dependent characteristic temperatures, are found. According to the magnetic and thermal measurement data, the magnetic phase diagrams of HoFe3(BO3)(4) for the magnetic field parallel and perpendicular to the crystal axis are constructed.
