Abstract: One of the most exciting features of the hole centers CuO45- in doped cuprates is in their unusually complicated ground state as a result of electronic quasi-degeneracy. An additional hole, doped to the basic CuO46- cluster with the b1g hole can occupy both the same hybrid Cu3d-O2p orbital state resulting in a Zhang-Rice singlet 1A1g and the purely oxygen eu molecular orbital resulting in singlet or triplet 1,3Eu  term with the close energies. We present a detailed analysis of the (pseudo)-Jahn-Teller effect driven by the near-degeneracy within the (1A1g, 1,3Eu)-manifold.

Title: Spin-lattice relaxation of Nd3+ and Tb3+ in phosphate and sodium borate silica glasses
Authors: B.M. Epel, S.B. Orlinskii, R.M. Rakhmatullin and Yu.K. Rosenzweig

Abstract: The experimental study of the electron spin-lattice relaxation (SLR) of Nd3+ and Tb3+ ions in phosphate and sodium borate silica glasses was performed. Measurements were made with electron spin echo technique. Temperature dependences of spin-lattice relaxation of the rare earth ions reveal the contribution of different relaxation mechanisms. A stepped like change of the SLR rate observed for Tb3+ and Nd3+ ions was explained by cross relaxation.

Title: EPR of the transition metal ions in micro-plasma coatings on aluminum alloy D16
Authors: A. Sinicin, S. Borcov, V. Nadolinny*, I. Kireenko, V. Kirillov
Address: Institute of Inorganic Chemistry Siberian Branch of RAS, Novosibirsk, Russia
*e-mail:

Abstract: The influence of micro plasma oxidation (MPO) process conditions on creation of the Al2O3 coatings on aluminum alloy D16 was studied using EPR technique. Aluminum alloy D16 contains alloyed transition metals such as Cu, Mn, Fe, Ni, Ti, being incorporated into the coatings structure during MPO processes. EPR data on transition metal ions allow estimating an appearance of a high temperature phase of Al2O3 due to difference in incorporation coefficients and in the EPR parameters of transition metal ions in low and high temperature Al2O3 phases of MPO coatings. These data show that no high temperature Al2O3 phases were created during anodic MPO process.

Title: Binding energy of a Cooper pairs with non-zero center of mass momentum in d-wave superconductors
Authors: M.V. Eremin, I.E. Lyubin*
Address: Kazan State University, Kremlevskaya, 18, Kazan 420008, Russia
*e-mail:

Abstract: The binding energy of Cooper pairs has been calculated for the case of d-wave symmetry of the superconducting gap in layered cuprate superconductors. We assume that Cooper pairs are formed by the short range potential and then derive the binding energy in the form \Delta _{{\mathbf{kq}}} = \Delta _x ({\mathbf{q}})\cos k_x a + \Delta _y ({\mathbf{q}})\cos k_y a + \Omega _x ({\mathbf{q}})\sin k_x a + \Omega _y ({\mathbf{q}})\sin k_y a, where q  is a total momentum of the pair. Numerical solutions of the self-consistent system of the integral equations for quantities \Delta _x ({\mathbf{q}}) , \Delta _y ({\mathbf{q}}) and \Omega _x ({\mathbf{q}}), \Omega _y ({\mathbf{q}}) along different lines in qx, qy  plane have been obtained. Anisotropy of the depairing total momentum (or depairing current) has been calculated.

*e-mail:

Abstract: Anthraquinone paramagnetic complexes have been used to study electron-acceptor centers on the surface of alumina modified with alkali metal ions (Li+, Na+, K+). Complexes have been characterized by CW EPR, ENDOR and pulse EPR (HYSCORE) techniques. It has been shown that alkali metal ions decreased the strength of electron-acceptor centers due to the inductive effect. As a result the concentration of anthraquinone complex with two Lewis acid sites (LAS) decreased, but the concentration of complex with one LAS increased with the increasing of alkali metal content. At large alkali metal concentration other kinds of anthraquinone paramagnetic complexes are formed, that are anthrasemiquinone weakly bound with LAS as well as anthrasemiquinone ion pair with alkali metal cation (lithium).

Keywords: EPR, ENDOR, HYSCORE, electron-acceptor centers, paramagnetic complexes of anthraquinone, alumina, aluminates

Abstract: Electron states near the surface of small metal particle caused by an image charge (image-potential states) have been investigated. The wave functions were calculated and the energy spectrum of these states was found depending on particle size. To estimate the influence of static magnetic field on the image-potential states the model problem, in which electron is localized on a surface of a sphere in uniform magnetic field was solved. In this case the field dependence of the energy levels represents a complex level crossing structure.

*e-mail:

Abstract: The investigations of Ag-contaning tennantite, belonging to the group of tetrahedrite-based sulfides, were performed by means of copper nuclear quadrupole resonance (NQR) in a temperature range from 4.2 K up to 60 K. These experiments showed that copper nuclear spin-lattice relaxation rate T1-1 and nuclear spin-echo decay rate T2-1 depend on temperature in the same way as earlier studied samples with other impurity compositions. The obtained data are interpreted from the viewpoint of internal motions in the structure of tennantite. The analysis of copper NQR data at low temperatures points to magnetic phase transition near 60 K from paramagnetic phase to the phase, which resembles spin-glass-like constitution.

Abstract: The asphaltene powders have been studied by 1H NMR relaxation method, differential scanning calorimetry (DSC) and X-ray structure analysis. The asphaltene samples were extracted from three oils with different component and hydrocarbon-group compositions. It was found that free induction decays (FID) of various asphaltene samples contain Gaussian component with spin-spin relaxation times T2 about 10?20 μs, which was named a solid component. The detecting possibilities of equilibrium first-order phase transitions and non-equilibrium glass-transitions on temperature dependence of part Ps of solid component in the 1H NMR signal are presented. The 1H NMR relaxation and DSC methods to study temperature properties of asphaltenes are compared. The glass-transition temperatures of side aliphatic chains of asphaltene molecules are measured. We set up that crystallization of high-molecular side aliphatic chains of asphaltene molecules is possible.

Abstract: Temperature dependences of ferromagnetic resonance spectra of nanoparticles of magnetite dispersed in polyethylene glycol films and nickel in vaseline oil have been studied. Sharp changes in spectra position (g-value) and linewidth have been found for both systems in the temperature interval 60 - 100 K above glass transition point. These effects have not been observed for polyethylene glycol films prepared under external magnetic field. It has been shown that the effects observed are connected with formation of anisotropic aggregates from nanoparticles under magnetic field action. The main factors determining the temperature of spectra parameters changes are the matrix viscosity, particles translational mobility and spectrum sweeping time.

Abstract: X-band ESR of chemically dehydrofluorinated poly(vinylidene fluoride) films has been studied in the 150 ? 375 K temperature range. Dehydrofluorinated films reveal an ESR signal with g-factor close to that of the free electron. The ESR parameters (integral intensity, width, g-factor) of the samples depend on duration of the chemical reaction, storage conditions and temperature. Heating above 375 K modifies paramagnetic component of the samples stored in air irreversibly, probably, as a result of hydrogenous radicals desorption and/or removal of oxygen, hydroxyl groups and moisture from the samples on heating. The deviation from the Curie law has been revealed for all the investigated samples.

Abstract: Nuclear magnetic resonance (NMR), Raman spectroscopy and thermogravimetric methods were used to study the peculiarities of lithium ion replacement by protons in lithium metallates Li2MO3 (M=Ti, Zr). In this article we show that almost all protons in the final substitution products H2MO3 enter into the crystal structure. All protons in zirconium hydroxide belong to hydrogen-bonded OH-groups. Contrary, titanium hydroxide contains both hydrogen-bonded and isolated OH-groups. Protons in H2ZrO3 form hydrogen bonds weaker than in H2TiO3.

    Abstract: The effect of the heat treatment duration on the electron paramagnetic resonance signal amplitude of free radicals for various wood species was observed. It was found that the amplitude of the electron paramagnetic resonance signal grows linearly with the vacuum heat treatment duration. The quantitative measurements of color changes for various wood species (pine, spruce, larch, birch and small-leaved lime) were performed. It is found that results of EPR experiments and color measurements of heat treated samples correlate with each other.

    Abstract: Results of demagnetizing effect studies in yttrium iron garnet Y3Fe5O12 thin films are reported. Experiments were performed on X-Band of electron paramagnetic resonance spectrometer at room temperature. The ferromagnetic resonance (FMR) spectra were obtained for one-layer single crystal YIG films for different values of the applied microwave power. Nonlinear FMR spectra transformation by the microwave power increasing in various directions of magnetic field sweep was observed. It is explained by the influence of the demagnetization action of nonequilibrium magnons.
