Phonon anomalies with doping in superconducting oxychlorides Ca2-xCuO2Cl2
Blair W. Lebert, Hajime Yamamoto, Masaki Azuma +6
We measure the dispersion of the Cu-O bond-stretching phonon mode in the high-temperature superconducting parent compound CaCuOCl. Our density functional theory calcula…
Non-complicated EuTiO3 Structure
David S. Ellis, Hiroshi Uchiyama, Satoshi Tsutsui +3
A recently published paper [arXiv:1206.5417 ]showed strong incommensurate diffraction peaks in EuTiO3 around zone boundary R-points. We wish to convey that in our samples, and, it…
Phonon Softening and Dispersion in EuTiO3
David S. Ellis, Hiroshi Uchiyama, Satoshi Tsutsui +4
We measured phonon dispersion in single crystal EuTiO using inelastic x-ray scattering. A structural transition to an antiferrodistortive phase was found at a critical temperat…
Oxygen Phonon Branches in YBa2Cu3O7
L. Pintschovius, D. Reznik, W. Reichardt +6
We report results of inelastic neutron scattering measurements of phonon dispersions in optimally doped YBa2Cu3O6.95 and compare them with model calculations. The focus is on the i…
Evidence for Dynamic Charge Stripes in the Phonons of Optimally Doped YBCO
L. Pintschovius, Y. Endoh, D. Reznik +6
Inelastic neutron scattering investigations on optimally doped YBCO revealed a very pronounced temperature dependence in the Cu-O in-plane bond-stretching vibrations along the (010…
