Effect of pressure on the Raman modes of antimony
X. Wang, K. Kunc, I. Loa +2
The effect of pressure on the zone-center optical phonon modes of antimony in the A7 structure has been investigated by Raman spectroscopy. The A_g and E_g frequencies exhibit a pr…
Pressure-driven orbital reorientation and change in Mott-Hubbard gap in YTiO3
I. Loa, X. Wang, K. Syassen +4
We investigate the crystal structure of YTiO3 at high pressures up to 30 GPa by synchrotron x-ray powder diffraction (T = 295 K). The variation of the Ti--O bond lengths with press…
Transition from Mott insulator to superconductor in GaNbSe and GaTaSe under high pressure
M. M. Abd-Elmeguid, B. Ni, D. I. Khomskii +4
Electronic conduction in GaMSe (M=Nb;Ta) compounds with the fcc GaMoS-type structure originates from hopping of localized unpaired electrons (S=1/2) among w…
Structural properties of the sesquicarbide superconductor La2C3 at high pressure
X. Wang, I. Loa, K. Syassen +4
The effect of pressure on the structural properties of lanthanum sesquicarbide La2C3 (T_c = 13 K) has been investigated at room temperature by angle-dispersive powder x-ray diffrac…
Crystal structure of LaTiO_3.41 under pressure
I. Loa, K. Syassen, X. Wang +3
The crystal structure of the layered, perovskite-related LaTiO_3.41 (La_5Ti_5O_{17+δ}) has been studied by synchrotron powder x-ray diffraction under hydrostatic pressure up to 27…
