Аннотация: Deformation and the thermal expansion coefficient of ceramic samples of (Ba1 - x La (x) )Ti1 - x/4O3 solid solutions (x = 0, 0.026, 0.036, 0.054) were studied in the temperature range 120-700 K. Based on an analysis of the data obtained, the temperature-composition phase diagram is refined, and the temperature dependence of the polarization is calculated. The results are discussed in combination with the dielectric measurement data.

Аннотация: We report on the emergence of new lines in the optical spectrum of the PrFe3(BO3)(4) single crystal at the magnetic ordering temperature. The transitions between singlet crystal-field sublevels of Pr3+ ion with the same transformational properties, strictly forbidden for the trigonal D-3 point symmetry of this ion in PrFe3(BO3)(4), appear below the Neel temperature and grow in intensity as a square of the order parameter. We show that the phenomenon originates from the mixing of wave functions of different Pr3+ sublevels by the Pr-Fe exchange interaction.

Ключевые слова (''Своб.индексиров.''): sodium nitrite--raman scattering--spectrum--polar mode--polariton--ferroelectric--dispersion curves
Аннотация: Raman light scattering spectra of a ferroelectric sodium nitrite crystal is studied in the lattice mode region as the temperature is lowered from room temperature to 123 K. The existence of a Raman satellite corresponding to the soft lattice mode, i.e., transverse polar vibration responsible for the ferroelectric phase transition, is established for the first time. It is found that the intensity of the Raman scattering by the pseudo-scalar low-frequency A (2) mode exceeds the intensity of other lattice variations by an order of magnitude.

Аннотация: We have reported on the results of a complex investigation of iron disilicide FeSi2 using characteristic electron energy loss spectroscopy, inelastic electron scattering cross section spectroscopy, and X-ray photoelectron spectroscopy. It has been shown that the main peak in the spectra of inelastic electron scattering for FeSi2 is a superposition of two unresolved peaks, viz., surface and bulk plasmons. An analysis of the fine structure of the spectra of inelastic electron scattering cross section by their decomposition into Lorentzlike Tougaard peaks has made it possible to quantitatively estimate the contributions of individual energy loss processes to the resulting spectrum and determine their origin and energy. © 2016, Pleiades Publishing, Ltd.

Аннотация: This paper reports the development of new phosphors using the chemical unit cosubstituting solid solution design strategy. Starting from Lu3Al5O12, the Al3+-Al3+ couple in respective octahedral and tetrahedral coordination was simultaneously substituted by a Mg2+-Si4+ pair forming the Lu3(Al2-xMgx)(Al3-xSix)O12:Ce3+ (x = 0.5-2.0) series; as a result, the CeO8 polyhedrons were compressed and the emission got red-shifted from green to yellow together with the broadening. The evolution of, the unit cell, the local structural geometry as well as the optical properties of Ce3+ in these garnet creations, in response to the gradual Mg-Si substitution for Al-Al, were studied by combined techniques of structural refinement and luminescence measurements. The new composition Lu2.97Ce0.03Mg0.5Al4Si0.5O12 was comprehensively evaluated regarding its potential application in blue LED-driven solid state white lighting: the maximum emission is at 550 nm under ?ex = 450 nm; the internal and external quantum efficiencies can reach 85% and 49%, respectively; a 1-phosphor-converted wLED lamp fabricated using the as-prepared phosphor exhibits the luminous efficacy of 105 lm W-1, the correlated color temperature of 6164 K and the color rendering index (Ra) of 75.6. The new solid solution composition series is open for further optimization to enhance the competence for commercial consideration. © 2016 The Royal Society of Chemistry.

Аннотация: The aim of the work is to elucidate the origin of magnetization presence in austenitic Fe86Mn13C steel after dynamic loading. The observation of microstructures in the region of transition from FCC austenitic Fe86Mn13C steel to FK12 + FK14 type of Frank-Kasper tetrahedral close packed structure is described. We used the methods of optical microscopy, electron microscopy, electron diffraction and X-ray-diffraction to investigate the phase transition region. Changes of local magnetization were estimated by induction method. To explain the magnetization origin of the sample consisting of austenite grains and intergranular layers, which have Frank-Kasper's structure (FK12 + FK14) typical of beta-Fe-Mn, the local electronic structure has been investigated for intergranular layers. The local electron structure of FK12 and FK14 clusters have been simulated by method of self-consistent field to understand the nature of non-zero magnetization of the Fe87Mn13 alloy exposed by shock deformation. It was shown, that numbers of states with upward and downward spins are not equal. Therefore the occurrence of magnetization is possible. (c) 2009 Published by Elsevier Ltd

Аннотация: The magnetic ground state of CuB2O4 is incommensurate at T = 1.8 K and undergoes a continuous phase transition to a noncollinear commensurate antiferromagnetic state at T* similar to 10 K. Close to T* higher-order magnetic satellites are observed. Coexistence of long- and short-range magnetic order is observed in both magnetic phases. This suggests that the association of the Dzyaloshinskii-Moriya interaction and anisotropy leads to the formation of a magnetic soliton lattice.

Аннотация: This paper reports on measurements of the specific heat of Pb2CdWO6 made at temperatures ranging from 80 to 750 K and of Pb2YbTaO6 within the 350- to 700-K temperature range. First-order phase transitions from the cubic phase at 677.3 and 581 K, respectively, were observed, and their thermodynamic characteristics were determined. The entropy change on the phase transitions is close to Rln4 for both compounds. The results obtained are discussed in terms of the model of position disordering of the lead ions. It was established that below 350 K, Pb2CdWO6 can exist in two states, stable and metastable, depending on the sample thermal prehistory. (C) 2002 MAIK "Nauka/Interperiodica".

Аннотация: Three types of optical magnetic-field induced second harmonic (MFISH) generation are observed in CuB2O4. Unusually sharp and intense electronic transitions in MFISH and linear absorption spectra provide selective access to the two nonequivalent Cu2+ sublattices. The magnetic phase diagram for both sublattices is determined by MFISH. Magnetic structure is dominated by antiferromagnetic order at the 4b site. Sublattice interactions transfer it to the 8d site where it coexists with a discoupled paramagnetic component.
