• W2008093432 abstract "We studied the Cu substitution by Co in ${mathrm{YBa}}_{2}$${mathrm{Cu}}_{3}$${mathrm{O}}_{6+mathit{x}}$. The samples have been analyzed by extended x-ray-absorption fine structure (EXAFS) and x-ray absorption near-edge structure (XANES) techniques in the oxidized and the reduced forms. We determined the Co cations average coordination and valence. Structural models for the arrangement around the cobalt atoms are proposed. The cobalt valence is ${3}^{+}$ in both oxidized and reduced forms. XANES experiments showed that the coordination polyhedra around the cobalt cations are not centrosymmetrical. EXAFS spectra showed that the cobalt cations are displaced from the (000) position and are surrounded by 5 oxygen atoms (4 at 1.82 AA{} and 1 at 2.02 AA{}). Both the EXAFS and XANES show that the difference between these two sets of Co-O distances decreases for reduced compounds. This corresponds to a slight increase of the site symmetry. Tetrahedral, pyramidal, and highly distorted octahedral coordinations for the cobalt cations are proposed. They take into account all these results obtained for oxidized and reduced compounds. Our results corroborate the assumption that the Co cations in the ${mathrm{YBa}}_{2}$(${mathrm{Cu}}_{1mathrm{ensuremath{-}}mathit{y}}$${mathrm{Co}}_{mathit{y}}$${)}_{3}$${mathrm{O}}_{6+mathit{x}}$ compounds are in the intermediate spin state with a mixing of high-spin ${mathrm{Co}}^{3+}$ in the tetrahedral site and low-spin ${mathrm{Co}}^{3+}$ in the distorted octahedral site." @default.
