V. R. Galakhov,M. Demeter,S. Bartkowski,Martin Neumann,N. A. Ovechkina,Ernst Z. Kurmaev,N. I. Lobachevskaya,Ya. M. Mukovskii,John F. Mitchell,David L. Ederer +9 more
TL;DR: In this article, the authors presented Mn $3s$ x-ray photoelectron spectra of manganese oxides with the Mn formal valency from $2+$ to $4+.
Journal ArticleDOI
Electronic structure of titanium monoxide
S. Bartkowski,Martin Neumann,Ernst Z. Kurmaev,V. V. Fedorenko,S. N. Shamin,V. M. Cherkashenko,S. N. Nemnonov,Antoni Winiarski,D. C. Rubie +8 more
TL;DR: In this paper, the electronic structure of the monoclinic phase of titanium monoxide and a vacancy-free rock-salt phase have been investigated using x-ray photoelectron spectroscopy and X-ray emission spectrographs.
Journal ArticleDOI
Valence-band spectra and electronic structure of CuFeO 2
V. R. Galakhov,A. I. Poteryaev,Ernst Z. Kurmaev,V. I. Anisimov,S. Bartkowski,Martin Neumann,Z. W. Lu,B. M. Klein,Tong-Rong Zhao +8 more
TL;DR: In this paper, a delafossite-type single crystal was studied by means of x-ray emission and X-ray photoelectron spectroscopy, and the results of the local spin density approximation (LSDA) (fullpotential linearized augmented plane wave method and linearized muffin-tin orbitals in atomic sphere approximation method) and $\mathrm{LSDA}+U$ calculations were compared with the experimental results and the LSDA calculations gave a correct description of the Cu and Fe $3d$ positions relative to the Fermi level
Journal ArticleDOI
Electronic structure of VO2 studied by x-ray photoelectron and x-ray emission spectroscopies
Ernst Z. Kurmaev,V. M. Cherkashenko,Yu. M. Yarmoshenko,S. Bartkowski,Andrei Postnikov,Manfred Neumann,Laurent Duda,Jinghua Guo,Joseph Nordgren,V. A. Perelyaev,W. Reichelt +10 more
TL;DR: In this paper, the authors performed first-principles tight-binding LMTO band-structure calculations for monoclinic and tetragonal rutile phases and compared the densities of states (DOS) with the experimental data.
Journal ArticleDOI
Core-level spectroscopic study of FeO and Fe S 2
TL;DR: In this paper, the authors compared the excitation spectra for charge neutral excitation (x-ray emission) and ionization (photoelectron spectroscopy) at the 2p$ edge and with final-state $3s$ holes.
