Anharmonicity of the antiferrodistortive soft mode in barium zirconate BaZrO
Petter Rosander, Erik Fransson, Cosme Milesi-Brault +6
Barium zirconate (BaZrO) is one of the very few perovskites that is claimed to retain an average cubic structure down to \SI{0}{\K}, while being energetically very close to an…
Bulk charge density wave and electron-phonon coupling in superconducting copper oxychlorides
Laura Chaix, Blair W. Lebert, Hu Miao +18
Bulk charge density waves are now reported in nearly all high-temperature superconducting cuprates, with the noticeable exception of one particular family: the copper oxychlorides.…
An Inelastic X-Ray investigation of the Ferroelectric Transition in SnTe
Christopher D. ONeill, Dmitry A. Sokolov, Andreas Hermann +4
We report that the lowest energy transverse-optic phonon in metallic SnTe softens to near zero energy at the structural transition at and importantly show that t…
Non-adiabatic effects in the phonon dispersion of Mg 1--x Al x B 2
Matteo D'Astuto, Rolf Heid, Burkhard Renker +7
Superconducting MgB shows an E zone center phonon, as measured by Raman spectroscopy, that is very broad in energy and temperature dependent. The Raman shift and lifet…
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…
Cube-shape diffuse scattering and the ground state of
A. Cervellino, S. N. Gvasaliya, B. Roessli +6
A quite unusual diffuse scattering phenomenology was observed in the single-crystal X-ray diffraction pattern of cubic perovskite BMT ($\mathrm{BaMg}_{1/3}\mathrm{Ta}_{2/3}\mathrm{…
