Karazin popup.description2 The object of the study is strongly correlated multi-electron lattice models of the Heisenberg and Hubbard models that are suitable for an adequate description of peculiarities of the magnetic characteristics of quasi-one-dimensional materials with magnetic sublattices of ladder and chain type (nanostructured magnetic materials).Purpose - development of new methods for modeling the features of magnetic properties of quasi-one-dimensional models of nanostructured magnets on the basis of transition metal compounds. Experimental search for new low-dimensional magnetics based on IRS of transition metals.Methods of investigation are the spin formalism of the valence bond method, the perturbation theory and effective low energy Hamiltonians; numerical methods for solving the eigenvalue problem, analytical methods of quantum solid state theory. In this work, we construct effective theoretical models that describe the low-energy states of complex compounds of transition metals with magnetic sublattices of ladder and chain type. Synthesized single crystals of catalytic converters of bisethylenediotetratiophyllulan (ET) with anions [8,8'-Hal2-3,3'-Fe (1,2-C2B9H10) 2]; where Hal is Cl, Br, I; single crystals of CRC (ET) [Re2Br8] and (ET) [Re2Br6 (CH3COO)] o 0.5 C2H3Cl3. For these compounds, the structure, conductivity and magnetic properties are determined. Product Description popup.authors Букриньов О Вітушкіна С. Звягін А. Комихов С. Кравченко А. Кравченко О.
