Аннотация: Anisotropy mechanisms in compounds with S-state ions are discussed, including the 'single-ion' exchange mechanism that was developed theoretically by Nikiforov and coworkers based on the two-ion model and which has only recently received detailed experimental study. Results demonstrating the significant role of the 'single-ion' source are presented. An independent generalized method for quantitatively describing and predicting the anisotropy of magnetically ordered crystals is discussed, and its potential for the investigation of the BiFeO3 multiferroic in the region of the existence of a spin cycloid is examined. The anisotropic interactions responsible for the formation of nanostructures in the form of spin vortices (skyrmions) in MnSi and Cu2OSeO3 are analyzed.

Заглавие : Anisotropy of dipole-dipole interactions in ferroelectric langmuir films of poly(vinylidene fluoride-trifluoroethylene)

Аннотация: The Lorentz tensor components L (j) for poly(vinylidene fluoride-trifluoroethylene, 70/30) Langmuir-Blodgett films in the ferroelectric phase are determined experimentally. The results indicate that intralayer dipole-dipole interaction between the segments of the polymer is stronger than interlayer interaction. This conclusion agrees with the absence of the critical film thickness below which ferroelectricity would cease to exist.

Аннотация: The magnetoresonance and dielectric properties of a number of crystals of a new family of multiferroics, namely, rare-earth ferroborates RFe(3)(BO(3))(4) (R = Y, Eu, Pr, Tb, Tb(0.25)Er(0.75)), are studied in the submillimeter frequency range (nu = 3-20 cm(-1)). Ferroborates with R = Y, Tb, and Eu exhibit permittivity jumps at temperatures of 375, 198, and 58 K, respectively, which are caused by the R32 - P3(1)2(1) phase transition. Antiferromagnetic resonance (AFMR) modes in the subsystem of Fe(3+) ions are detected in the range of antiferromagnetic ordering (T T(N)

Заглавие : Bifurcations of coupled electron-phonon modes in an antiferromagnet subjected to a magnetic field
Место публикации : Phys. Rev. Lett.: American Physical Society, 2017. - Vol. 118, Is. 16. - Ст.167203. - ISSN 00319007 (ISSN), DOI 10.1103/PhysRevLett.118.167203

Аннотация: We report on a new effect caused by the electron-phonon coupling in a stoichiometric rare-earth antiferromagnetic crystal subjected to an external magnetic field, namely, the appearance of a nonzero gap in the spectrum of electronic excitations in an arbitrarily small field. The effect was registered in the low-temperature far-infrared (terahertz) reflection spectra of an easy-axis antiferromagnet PrFe3(BO3)4 in magnetic fields Bext-c. Both paramagnetic and magnetically ordered phases (including a spin-flop one) were studied in magnetic fields up to 30 T, and two bifurcation points were observed. We show that the field behavior of the coupled modes can be successfully explained and modeled on the basis of the equation derived in the framework of the theory of coupled electron-phonon modes, with the same field-independent electron-phonon interaction constant |W|=14.8 cm-1. © 2017 American Physical Society.

Аннотация: The synthesis of nanoparticles inside microorganisms is an economical alternative to chemical and physical methods of nanoparticle synthesis. In this study, ferrihydrite nanoparticles synthesized by Klebsiella oxytoca bacterium in special conditions were characterized by scanning electron microscopy (SEM), energy-dispersive X-ray analysis (EDS), small-angle X-ray (SAXS), UV-Vis spectroscopy, fluorescence, fluorescence resonance energy transfer (FRET), and molecular docking. The morphology and the structure of the particles were characterized by means of SEM and SAXS. The elemental content was determined by means of the EDS method. The absorption properties of the ferrihydrite nanoparticles were investigated by UV-Vis spectroscopy. The binding mechanism of the biogenic ferrihydrite nanoparticles to Bovine Serum Albumin (BSA) protein, studied by fluorescence, showed a static and weak process, combined with FRET. Protein denaturation by temperature and urea in the presence of the ferrihydrite nanoparticles demonstrated their influence on the unfolding process. The AutoDock Vina and UCSF Chimera programs were used to predict the optimal binding site of the ferrihydrite to BSA and to find the location of the hydrophobic cavities in the sub-domain IIA of the BSA structure.

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.

Заглавие : Bridging behaviour of the 2-thiobarbiturate anion in its complexes with LiI and NaI
Место публикации : Acta Crystallographica Section C Crystal Structure Communications. - 2013. - Vol. 69, Pt. 7. - P.704-708. - ISSN 0108-2701, DOI 10.1107/S0108270113014078

Аннотация: The structures of the LiI and NaI salts of 2-thiobarbituric acid (2-sulfanylidene-1-3-diazinane-4,6-dione, H 2TBA) have been studied. μ-Aqua-octaaquabis(μ-2- thiobarbiturato-κ2 O:O′)bis(2-thiobarbiturato-κO) tetralithium(I) dihydrate, [Li4(C4H3N 2O2S)4(H2O)9]·2H 2O, (I), crystallizes with four symmetry-independent four-coordinated LiI cations and four independent HTBA- anions. The structure contains two structurally non-equivalent LiI cations and two non-equivalent HTBA- anions (bridging and terminal). Eight of the coordinated water ligands are terminal and the ninth acts as a bridge between LiI cations. Discrete [Li4(HTBA)4(H2O)9] ·2H2O complexes form two-dimensional layers. Neighbouring layers are connected via hydrogen-bonding interactions, resulting in a three-dimensional network. Poly[μ2-aqua-tetraaqua(μ4-2- thiobarbiturato-κ4 O:O:S:S)(μ2-thiobarbiturato- κ2 O:S)disodium(I)], [Na2(C4H 3N2O2S)2(H2O) 5] n , (II), crystallizes with six-coordinated NaI cations. The octahedra are pairwise connected through edge-sharing by a water O atom and an O atom from the μ4-HTBA- ligand, and these pairs are further top-shared by the S atoms to form continuous chains along the a direction. Two independent HTBA- ligands integrate the chains to give a three-dimensional network. © 2013 International Union of Crystallography.

Аннотация: We performed inelastic neutron scattering measurements on CuB2O4 with a magnetic field applied in the tetragonal basal plane. The spin dynamics in this cuprate is determined by the interplay of two magnetic Cu2+ subsystems, the magnetic cage with predominant 3d Heisenberg exchange and quasi Id zig-zag chains. The comparison of the dispersion spectra along the chain direction in zero field and under applied field suggests a decoupling of the two magnetic sublattices under field. (c) 2006 Elsevier B.V.
