Elasto-Raman scattering: arsenic optical phonon as a probe of nematicity in BaFeAs
J. -C. Philippe, J. Faria, A. Forget +5
We report a Raman scattering study of nematic degrees of freedom in the iron-based superconductor parent compound BaFeAs under tunable uniaxial strain. We demonstrate that…
Raman scattering study of Spin-Density-Wave order and electron-phonon coupling in Ba(FeCo)As
L. Chauvière, Y. Gallais, M. Cazayous +4
We report Raman scattering measurements on iron-pnictide superconductor Ba(FeCo)As single crystals with varying cobalt content. The electronic Raman continu…
Impact of the Spin Density Wave Order on the Superconducting Gap of Ba(FeCo)As
L. Chauvière, Y. Gallais, M. Cazayous +4
We report a doping dependent electronic Raman scattering measurements on iron-pnictide superconductor Ba(FeCo)As single crystals. A strongly anisotropic gap is…
Polar phonons and spin excitations coupling in multiferroic BiFeO3 crystals
P. Rovillain, M. Cazayous, Y. Gallais +4
Raman scattering measurements on BiFeO3 single crystals show an important coupling between the magnetic order and lattice vibrations. The temperature evolution of phonons shows tha…
Evidence for two distinct energy scales in the Raman spectra of YBa2(CuNi)O6.95
Y. Gallais, A. Sacuto, P. Bourges +3
We report low energy electronic Raman scattering from Ni-substituted YBa2Cu3O6.95 single crystals with Tc ranging from 92.5 K to 78 K. The fully symmetrical A1g channel and the B1g…
