Observation of low energy dispersive modes in un- derdoped (La, Nd) 2--x Sr x CuO 4
Matteo D 'Astuto, Sylvain Denis, Jeff Graf +10
We find excitations lower in energy than known phonon modes in underdoped LaSrCuO (x=0.08), with both inelastic X-Ray scattering (IXS) and inelastic neutron…
Understanding the complex phase diagram of uranium: the role of electron-phonon coupling
S. Raymond, J. Bouchet, G. H. Lander +8
We report an experimental determination of the dispersion of the soft phonon mode along [1,0,0] in uranium as a function of pressure. The energies of these phonons increase rapidly…
Phonon Density of States in Nd(OF)FeAs
M. Le Tacon, M. Krisch, A. Bosak +2
We report measurements of the phonon density-of-states in iron oxypnictide superconductors by inelastic x-ray scattering. A good agreement with ab-initio calculations that do not t…
High frequency acoustic modes in liquid gallium at the melting point
T. Scopigno, A. Filipponi, M. Krisch +3
The microscopic dynamics in liquid gallium (l-Ga) at melting (T=315 K) has been studied by inelastic x-ray scattering. We demonstrate the existence of collective acoustic-like mode…
Phonon anomalies at the valence transition of SmS : An inelasticX-ray scattering study under pressure
S. Raymond, J. P. Rueff, M. D'Astuto +3
The phonon dispersion curve of SmS under pressure was studied by inelastic x-ray scattering around the pressure-induced valence transition. A significant softening of the longitudi…
Anomalous Dispersion of Longitudinal Optical Phonons in Determined by Inelastic X-ray Scattering
M. d'Astuto, P. K. Mang, P. Giura +7
The phonon dispersions of along the direction have been determined by inelastic x-ray scattering. Compared to the undoped parent co…
