Multigap superconductivity and strong electron-boson coupling in Fe-based superconductors: A point-contact Andreev-reflection study of Ba(Fe1-xCox)2As2 single crystals
M. Tortello, D. Daghero, G. A. Ummarino +5
Directional point-contact Andreev-reflection (PCAR) measurements in Ba(Fe1-xCox)2As2 single crystals (Tc=24.5 K) indicate the presence of two superconducting gaps with no line node…

Conductance asymmetry in point-contacts on epitaxial thin films of Ba(FeCo)As
Manan Mehta, Goutam Sheet, D. A. Dikin +8
Point-contact spectroscopy is a powerful tool for probing superconductors. One of the most common observations in the point-contact spectra on the recently discovered ferropnictide…
