Особенности кристаллической структуры и магнитные свойства соединения DyFeTi2O7 / Т. В. Дрокина [и др.] // Физ. тверд. тела. - 2013. - Т. 55, Вып. 10. - С. 1922-1927
Аннотация: Представлены результаты исследования особенностей кристаллической структуры и распределения катионов железа по позициям в соединении DyFeTi2O7, проведено сравнение с изоструктурным соединением GdGaTi2O7. Методами мессбауэровской спектроскопии и рентгеновской дифракции подтвержден атомный беспорядок в распределении ионов железа Fe3+ по структурным позициям в DyFeTi2O7. Результаты магнитных измерений в низкотемпературной области показывают излом на температурной зависимости магнитного момента и его зависимость от магнитной предыстории образца. Полученные экспериментальные данные позволяют сделать вывод о реализации состояния спинового стекла с температурой замерзания Tf=6 K в соединении DyFeTi2O7

Specific features of the crystal structure and magnetic properties of the DyFeTi2O7 compound / T. V. Drokina [et al.] // Phys. Solid State. - 2013. - Vol. 55, Is. 10. - P. 2037-2042, DOI 10.1134/S1063783413100107 . - ISSN 1063-7834
Аннотация: Results of studying the specific features of formation of the crystal structure and distribution of iron cations over the sites in the DyFeTi2O7 compound have been presented and the comparison with the GdGaTi2O7 isostructural compound has been performed. The atomic disorder in the distribution of the Fe3+ ions over structural sites in the DyFeTi2O7 compound is confirmed by the Mossbauer spectroscopy and X-ray diffractometry. The results of magnetic measurements in the low-temperature region have revealed an inflection point in the temperature dependence of the magnetic moment and its dependence on the magnetic prehistory of the sample. The obtained experimental data suggest that there is a spin glass state with freezing point Tf = 6 K in the DyFeTi2O7 compound. В© 2013 Pleiades Publishing, Ltd.

Coexistence of superconductivity and antiferromagnetism in heavy-fermion intermetallic compound CeRhIn5 / V. V. Val'Kov, A. O. Zlotnikov // J. Supercond. Nov. Magn. - 2013. - Vol. 26, Is. 9. - P. 2885-2886, DOI 10.1007/s10948-013-2222-4 . - ISSN 1557-1939

Coexistence superconductivity antiferromagnetism -- Heavy-fermion systems -- Periodic Anderson model
Аннотация: An interference of heavy-fermion superconductivity (SC) and antiferromagnetism (AFM) has been studied in the framework of the periodic Anderson model with the superexchange interaction between localized electrons. It has been shown that pressure-induced energy change of the localized states leads to modifying antiferromagnetic and superconducting order parameters. Conditions have been found for the coexistence of SC and AFM in the model. Theoretical results of the pressure effects on the ground state character of the heavy-fermion systems are in good agreement with experimental data for a rare-earth intermetallic compound CeRhIn5. The divergence of the effective electron mass produced by suppressing the long-range antiferromagnetic order has also been analyzed in the same framework.

    Jc enhancement and flux pinning of Se substituted YBCO compound / Z. D. Yakinci [et al.] // J. Mater. Sci.: Mater. Electron. - 2013. - Vol. 24. - P. 4790–4797, DOI 10.1007/s10854-013-1476-8. - The work is supported by Project No. 7 of RAS Program ‘"Quantum physics of condensed matter" . - ISSN 0957-4522
   Перевод заглавия: Увеличение критического тока и пиннинг потока в соединении YBCO с замещением Se
Аннотация: Y2/3 Se1/3Ba2Cu3Ox compound was fabricated by using solid state fabrication technique. Optimum heat treatments conditions for Y0.77Se0.33Ba2Cu3Ox were investigated. It was determined that the XRD results of these samples were similar to Y-123 phase with some impurities. Magnetization dependence of applied magnetic fields was measured in the range of 0-9В T at 10-50В K. The symmetric and asymmetric M-H loops were obtained for the samples. Magnetization loops obtained from measurements were successfully described by the extended Valkov-Khrustalev model. The temperature and applied magnetic field dependencies of magnetization of sample were estimated and critical current density of samples was calculated by Bean model and pinning force of samples was calculated by using Lorentz force. It is found from critical current density values that Se additions were acted as a pinning center which increased critical current density. В© 2013 Springer Science+Business Media New York.

Аннотация: The X-ray diffraction, Mossbauer, calorimetric, and magnetic characteristics of zirconolite GdFeTi2O7 have been measured to determine the ground magnetic state. A kink dependent on the magnetic prehistory of the sample has been revealed in the temperature dependence of the magnetic moment at T = 3 K. Mossbauer spectroscopy has confirmed the nonequivalence of the iron ion positions in GdFeTi2O7. The experimental data obtained allow the conclusion on the formation of a spin glass state with the freezing temperature T (f) = 3 K in the GdFeTi2O7 compound.

Аннотация: The results of the experimental investigation of the magnetic properties of the SmFeGe2O7 compound have been presented. It has been found that the temperature dependence of the susceptibility exhibits two features that coincide with the anomalies in the temperature dependence of the specific heat and indicate magnetic phase transitions in SmFeGe2O7. The external magnetic field induces a magnetic transition, the critical field of which depends on the temperature.

Аннотация: The interaction of the conformational degrees of freedom of azomethines in the nematic phase, which is induced by electronic donor-acceptor properties of the terminal substituents of the benzylideneaniline core is studied. These degrees of freedom related to the rotation angles phi (k) around the bonds between the substituent and the aniline ring (phi(1)) and also between the CH=N bridge and the aniline ring (omega(2)) are characterized by the parameters Q (k) = aOE (c) cos(2)phi (k) >. It is found that the interaction of these degrees of freedom is manifested in the linear dependence Q (2)(Q (1)). Within the phenomenological theory the effect of this interaction on changes delta (k) in the Q (k) values during the nematic liquid crystal-isotropic liquid phase transition is revealed along with the temperature T (NI) and character of this transition. The derivation of previously established empirical dependences T (NI)(Q (k) ) is presented in the presence of direct and indirect steric effects of side substituents affecting the Q (k) values. A diverse combination of delta (k) signs in the nematic phase, which is a prerequisite for the conformational polymorphism of the nematic phases of azomethines, is shown.
