Anisotropy of the paramagnetic susceptibility in LaTiO3_{3}: The electron-distribution picture in the ground state

The energy-level scheme and wave functions of the titanium ions in LaTiO$_{3}$ are calculated using crystal-field theory and spin-orbit coupling. The theoretically derived temperature dependence and anisotropy of the magnetic susceptibility agree well with experimental data obtained in an untwinned single crystal. The refined fitting procedure reveals an almost isotropic molecular field and a temperature dependence of the van Vleck susceptibility. The charge distribution of the 3d--electron on the Ti positions and the principle values of the quadrupole moments are derived and agree with NMR data and recent measurements of orbital momentum $$ and crystal-field splitting. The low value of the ordered moment in the antiferromagnetic phase is discussed.Comment: 6 pages, 2 figures, 3 table

Thematic Scientific Bibliography as a Discourse: Modern Youth Values

The experience of collecting and systematizing scientific sources from different humanitarian fields, united by a common theme — values in the modern youth environment are described in the article. This content brings the article closer to the genre of an interdisciplinary bibliographic review. The practical task of the review is to prepare a bibliographic reference manual for publication. The selection of scientific publications was based on key axiological concepts, as well as on the idea of youth as a demographic and sociocultural group of people from 14 to 30 years old, on the way to becoming psychophysiological maturity and socialization. Conclusions of a theoretical nature are connected with the identification of general patterns of development of youth axiological issues: consideration of values within the framework of individual types (moral, political, religious, family, etc.); the predominance of works devoted to the study of the mutual influence of values and the sociocultural environment; the predominant interest of scientists in the study of spiritual, moral and socio-political values; the tendency of the last 5 years to highlight the values of communication and information as an independent object of axiological research. The practical task of compiling a bibliographic manual is solved in the form of determining the main principle of rubrication, which is the subject-thematic (typological) approach

Analysis of Vocabulary Definitions of the Word “Uspech” (“Success”): Problem of Verification of Linguoculturological Constructions

A method for solving the actual problem of verification of linguocultural constructions is proposed. Attention is paid to the establishment of the correctness and effectiveness of the application of one of the types of semantic analysis in modern linguistic studies devoted to the concept of “success” and its lexical representatives. The proposed meta-research approach is aimed at identifying and searching for the causes of significant discrepancies in the results of definitional analysis when the theoretical base, scientific apparatus and research strategy coincide. This approach allows the author to consider a number of controversial cases of the use of definitional analysis associated with its object, subject and metalanguage, and to solve some important methodological issues: what kind of linguistic sources are involved in collecting material; how the definitional analysis of a polysemantic word is carried out; in what aspect the interlingual comparison of the dictionary definitions of one word is carried out; what advantages and disadvantages of different formats for describing semantic components are identified as a result of definitional analysis, etc. Critical analysis of research techniques alternates with constructive sentences for the semantic analysis of the dictionary definitions of the word success in modern Russian. General observations on the features of the application of the analytical method under consideration are proposed as conclusions

Anisotropic Exchange in LiCuVO4_4 probed by ESR

We investigated the paramagnetic resonance in single crystals of LiCuVO$_4$ with special attention to the angular variation of the absorption spectrum. To explain the large resonance linewidth of the order of 1 kOe, we analyzed the anisotropic exchange interaction in the chains of edge-sharing CuO$_6$ octahedra, taking into account the ring-exchange geometry of the nearest-neighbor coupling via two symmetric rectangular Cu-O bonds. The exchange parameters, which can be estimated from theoretical considerations, nicely agree with the parameters obtained from the angular dependence of the linewidth. The anisotropy of this magnetic ring exchange is found to be much larger than it is usually expected from conventional estimations which neglect the bonding geometry. Hence, the data yield the evidence that in copper oxides with edge-sharing structures the role of the orbital degrees of freedom is strongly enhanced. These findings establish LiCuVO$_4$ as one-dimensional compound at high temperatures. PACS: 76.30.-v, 76.30.Fc, 75.30.EtComment: 18 pages, 6 figure

Spin correlations and Dzyaloshinskii-Moriya interaction in Cs2_2CuCl4_4

We report on electron spin resonance (ESR) studies of the spin relaxation in Cs$_2$CuCl$_4$. The main source of the ESR linewidth at temperatures $T \leq 150$ K is attributed to the uniform Dzyaloshinskii-Moriya interaction. The vector components of the Dzyaloshinskii-Moriya interaction are determined from the angular dependence of the ESR spectra using a high-temperature approximation. Both the angular and temperature dependence of the ESR linewidth have been analyzed using a self-consistent quantum-mechanical approach. In addition analytical expressions based on a quasi-classical picture for spin fluctuations are derived, which show good agreement with the quantum-approach for temperatures $T \geq 2J/k_{\rm B} \approx 15$ K. A small modulation of the ESR linewidth observed in the $ac$-plane is attributed to the anisotropic Zeeman interaction, which reflects the two magnetically nonequivalent Cu positions

Anisotropic Exchange in LiCu2O2{\bf LiCu_2O_2}

We investigate the magnetic properties of the multiferroic quantum-spin system LiCu$_2$O$_2$ by electron spin resonance (ESR) measurements at $X$- and $Q$-band frequencies in a wide temperature range $(T_{\rm N1} \leq T \leq 300$\,K). The observed anisotropies of the $g$ tensor and the ESR linewidth in untwinned single crystals result from the crystal-electric field and from local exchange geometries acting on the magnetic Cu$^{2+}$ ions in the zigzag-ladder like structure of LiCu$_2$O$_2$. Supported by a microscopic analysis of the exchange paths involved, we show that both the symmetric anisotropic exchange interaction and the antisymmetric Dzyaloshinskii-Moriya interaction provide the dominant spin-spin relaxation channels in this material.Comment: 10 pages, 10 Figure

Electron spin resonance and exchange paths in the orthorhombic dimer system Sr2VO4

We report on magnetization and electron spin resonance (ESR) measurements of Sr$_{2}$VO$_4$ with orthorhombic symmetry. In this dimer system the $V^{4+}$ ions are in tetrahedral environment and are coupled by an antiferromagnetic intra-dimer exchange constant $J/k_B \approx$ 100 K to form a singlet ground state without any phase transitions between room temperature and 2 K. Based on an extended-H\"{u}ckel-Tight-Binding analysis we identify the strongest exchange interaction to occur between two inequivalent vanadium sites via two intermediate oxygen ions. The ESR absorption spectra can be well described by a single Lorentzian line with an effective g-factor $g$ = 1.89. The temperature dependence of the ESR intensity is well described by a dimer model in agreement with the magnetization data. The temperature dependence of the ESR linewidth can be modeled by a superposition of a linear increase with temperature with a slope $\alpha$ = 1.35 Oe/K and a thermally activated behavior with an activation energy $\Delta/k_B$ = 1418 K, both of which point to spin-phonon coupling as the dominant relaxation mechanism in this compound.Comment: 5 pages, 4 figure
