Two pressure-induced structural phase transitions in TiOCl
J. Ebad-Allah, A. Schönleber, S. van Smaalen +7
We studied the crystal structure of TiOCl up to pressures of =25~GPa at room temperature by x-ray powder diffraction measurements. Two pressure-induced structural phase transiti…
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…
Pressure-induced metallization and structural phase transition of the Mott-Hubbard insulator TiOBr
C. A. Kuntscher, S. Frank, A. Pashkin +9
We investigated the pressure-dependent optical response of the low-dimensional Mott-Hubbard insulator TiOBr by transmittance and reflectance measurements in the infrared and visibl…
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.…
One-dimensional versus two-dimensional correlation effects in the oxyhalides TiOCl and TiOBr
M. Hoinkis, M. Sing, S. Glawion +6
We have performed a comparative study of the electronic structures of the spin-Peierls systems TiOCl and TiOBr by means of photoemission spectroscopy and density functional calcula…
Transport, magnetic, thermodynamic and optical properties in Ti-doped Sr_2RuO_4
K. Pucher, J. Hemberger, F. Mayr +9
We report on electrical resistivity, magnetic susceptibility and magnetization, on heat capacity and optical experiments in single crystals of Sr_2Ru_(1-x)Ti_xO_4. Samples with x=0…
