The effect of internal pressure on the tetragonal to monoclinic structural phase transition in ReOFeAs: the case of NdOFeAs
Michela Fratini, Rocchina Caivano, Alessandro Puri +10
We report the temperature dependent x-ray powder diffraction of the quaternary compound NdOFeAs (also called NdFeAsO) in the range between 300 K and 95 K. We have detected the stru…
Linear arrays of non homogeneous Cu sites in the CuO2 plane, a new scenario for pairing mechanisms in a currugated-iron-like plane
Antonio Bianconi
Experimental results obtained by using x-ray absorption spectroscopy show that the configurations of Cu sites in the CuO2 plane of Bi 2:2:1:2 high Tc superconductors are not homoge…
Multiband superconductors close to a 3D-2D electronic topological transition
G. G. N. Angilella, A. Bianconi, R. Pucci
Within the two-band model of superconductivity, we study the dependence of the critical temperature Tc and of the isotope exponent alpha in the proximity to an electronic topologic…
Diagonal charge stripes giving a suppression of spectral weight at selected spots on the Fermi surface
N. L. Saini, A. Bianconi, A. Lanzara +5
Here we report an asymmetric suppresion of spectral weight at the Fermi surface around the M points using angle resolved photoemission spectroscopy. The results provide direct evid…
