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…
The nodal gap component as a good candidate for the superconducting order parameter in cuprates
W. Guyard, A. Sacuto, M. Cazayous +4
Although more than twenty years have passed since the discovery of high temperature cuprate superconductivity, the identification of the superconducting order parameter is still un…
Investigations on the relationship between and the superconducting gap under magnetic and non-magnetic impurity substitutions in YBaCuO
M. Le Tacon, A. Sacuto, Y. Gallais +2
We report electronic Raman scattering measurements on optimally doped YBa2Cu3O7 where Zn or Ni impurities have been substituted by Cu. Using Raman selection rules, we have probed t…
Two Energy Scales and two Quasiparticle Dynamics in the Superconducting State of Underdoped Cuprates
M. Le Tacon, A. Sacuto, A. Georges +4
The superconducting state of underdoped cuprates is often described in terms of a single energy-scale, associated with the maximum of the (d-wave) gap. Here, we report on electroni…
Coupling between quasiparticles and a bosonic mode in the normal state of HgBaCuO
Y. Gallais, M. Le Tacon, A. Sacuto +1
We report a doping dependent study of the quasiparticles dynamics in HgBaCuO via Electronic Raman Scattering. A well-defined energy scale is found in the normal state d…
Effects of Magnetic and non-Magnetic Impurities on the Superconducting State of YBaCuO
M. Le Tacon, A. Sacuto, Y. Gallais +3
We report Electronic Raman Scattering measurements on optimally doped Zn and Ni substituted YBCO in A and B channels. We show that the superconducting gap energy is i…
