Sharp optical phonon softening close to optimal doping in LaBaCuO
Matteo D'Astuto, Guy Dhalenne, Jeff Graf +6
We report a direct observation of a sharp Kohn-like anomaly in the doubly degenerate copper-oxygen bond-stretching phonon mode occurring at in La$_…
Bond stretching phonon softening and angle-resolved photoemission kinks in optimally doped Bi2Sr1.6La0.4Cu2O6 superconductors
J. Graf, M. d'Astuto, C. Jozwiak +7
We report the first measurement of the optical phonon dispersion in optimally doped single layer Bi2Sr1.6La0.4Cu2O6+delta using inelastic x-ray scattering. We found a strong soften…
Pressure-induced order-disorder phase transition in superconducting CaC6
A. Gauzzi, N. Bendiab, M. d'Astuto +9
By means of synchrotron X-ray diffraction, we studied the effect of high pressure, P, up to 13 GPa on the room temperature crystal structure of superconducting CaC6. In this P rang…
Low-q dispersion of transverse acoustic phonons in YBaCuO
Andrea Gauzzi, Matteo D'Astuto, Francesca Licci +2
High-resolution (=1.3 meV) inelastic X-ray scattering (IXS) in optimally doped untwinned YBaCuO single crystals show that the dispersion of transverse acoustic…
