Atomic Ordering in Cubic Bismuth Telluride Alloy Phases at High Pressure
I. Loa, J. -W. G. Bos, R. A. Downie +1
Pressure-induced transitions from ordered intermetallic phases to substitutional alloys to semi-ordered phases were studied in a series of bismuth tellurides. Using angle-dispersiv…
Structural transformations of Li2C2 at high pressures
Ilias Efthimiopoulos, Daryn E. Benson, Sumit Konar +9
Structural changes of Li2C2 under pressure were studied by synchrotron x-ray diffraction in a diamond anvil cell under hydrostatic conditions and by using evolutionary search metho…
Electronic Orders in the Verwey Structure of Magnetite
Mark Senn, Ingo Loa, Jon P. Wright +1
Electronic structure calculations of the Verwey ground state of magnetite, Fe3O4, using density functional theory with treatment of on-site Coulomb interactions (DFT+U scheme) are…
Plasmons in Sodium under Pressure: Increasing Departure from Nearly-Free-Electron Behavior
I. Loa, K. Syassen, G. Monaco +3
We have measured plasmon energies in Na under high pressure up to 43 GPa using inelastic x-ray scattering (IXS). The momentum-resolved results show clear deviations, growing with i…
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…
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…
