Metal-ligand interplay in strongly-correlated oxides: a parametrized phase diagram for pressure induced spin transitions
A. Mattila, J. -P. Rueff, J. Badro +2
We investigate the magnetic properties of archetypal transition-metal oxides MnO, FeO, CoO and NiO under very high pressure by x-ray emission spectroscopy at the Kβline. We observe…
Hard x-ray spectroscopy in NaxCoO2 and superconducting NaxCoO2 - yH2O: A view on the bulk Co electronic properties
Philippe Leininger, J. -P. Rueff, J. -M. Mariot +6
The electronic properties of Co in bulk Na0.7CoO2 and the superconducting hydrated compound Na0.35CoO2 - y H2O have been investigated by x-ray absorption spectroscopy (XAS) and res…
Evidence for non-conventional pairing in NaCoOyHO
Jean-Pascal Rueff, M. Calandra, M. D'astuto +10
We report on first investigation of the lattice dynamics in the novel superconducting material NaCoO1.3HO and the non-hydrated parent compound Na$\_{0.7}…
Temperature and pressure-induced spin-state transitions in LaCoO3
György Vankó, Jean-Pascal Rueff, Aleksi Mattila +2
We report the continuous variation of the spin moment of cobalt in LaCoO3 across its temperature and pressure-induced spin transitions evidenced with Kβemission spectra. The first…
