Point-contact Andreev-reflection spectroscopy in Fe(Te,Se) films: multiband superconductivity and electron-boson coupling
D. Daghero, P. Pecchio, G. A. Ummarino +6
We report on a study of the superconducting order parameter in Fe(TeSe) thin films (with different Se contents: x=0.3, 0.4, 0.5) by means of point-contact Andreev-ref…

Doping and critical-temperature dependence of the energy gaps in Ba(Fe_{1-x}Co_x)_2As_2 thin films
P. Pecchio, D. Daghero, G. A. Ummarino +4
The dependence of the superconducting gaps in epitaxial Ba(Fe_{1-x}Co_{x})_2As_2 thin films on the nominal doping x (0.04 \leq x \leq 0.15) was studied by means of point-contact An…

The order-parameter symmetry and Fermi surface topology of 122 Fe-based superconductors: a point-contact Andreev-reflection study
R. S. Gonnelli, M. Tortello, D. Daghero +8
We report on the results of directional point-contact Andreev-reflection (PCAR) measurements in Ba(Fe_{1-x}Co_x)2As2 single crystals and epitaxial c-axis oriented films with x = 0.…
