Muon-spin relaxation measurements on the dimerized spin-1/2 chains NaTiSi2O6 and TiOCl
P. J. Baker, S. J. Blundell, F. L. Pratt +10
We report muon spin relaxation (muSR) and magnetic susceptibility investigations of two Ti3+ chain compounds which each exhibit a spin gap at low temperature, NaTiSi2O6 and TiOCl.…
Mott-Hubbard gap closure and structural phase transition in the oxyhalides TiOBr and TiOCl under pressure
C. A. Kuntscher, A. Pashkin, H. Hoffmann +9
Pressure-dependent transmittance and reflectance spectra of TiOBr and TiOCl single crystals at room temperature suggest the closure of the Mott-Hubbard gap, i.e., the gap is filled…
Epitaxial growth of Fe3O4 thin films on ZnO and MgO substrates
A. Müller, A. Ruff, M. Paul +9
Magnetite thin fims have been grown epitaxially on ZnO and MgO substrates using molecular beam epitaxy. The film quality was found to be strongly dependent on the oxygen partial pr…
Self-organized atomic nanowires of noble metals on Ge(001): atomic structure and electronic properties
J. Schaefer, S. Meyer, C. Blumenstein +9
Atomic structures of quasi-one-dimensional (1D) character can be grown on semiconductor substrates by metal adsorption. Significant progress concerning study of their 1D character…
One-Electron Singular Branch Lines of the Hubbard Chain
J. M. P. Carmelo, K. Penc, L. M. Martelo +5
The momentum and energy dependence of the weight distribution in the vicinity of the one-electron spectral-function singular branch lines of the 1D Hubbard model is studied for all…
Hard X-ray photoemission spectroscopy of LaVO/SrTiO: Band alignment and electronic reconstruction
M. Stübinger, J. Gabel, P. Scheiderer +13
The heterostructure consisting of the Mott insulator LaVO and the band insulator SrTiO is considered a promising candidate for future photovoltaic applications. Not only do…
