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(Te1−x​Sex​) thin films (with different Se contents: x=0.3, 0.4, 0.5) by means of point-contact Andreev-ref…

Fermi-surface topological phase transition and horizontal order-parameter nodes in CaFe2​As2​ under pressure

R. S. Gonnelli, D. Daghero, M. Tortello +8

Iron-based compounds (IBS) display a surprising variety of superconducting properties that seems to arise from the strong sensitivity of these systems to tiny details of the lattic…
