A Point-Contact Study of the Superconducting Gaps in Al-Substituted and C-Substituted MgB_2 Single Crystals
R. S. Gonnelli, D. Daghero, G. A. Ummarino +6
We present the results of directional point-contact spectroscopy in state-of-the-art Mg_{1-x}Al_xB_2 and Mg(B_{1-y}C_{y})_2 single crystals produced at ETH, Zurich. Fitting the con…
Evidence for Single-gap Superconductivity in Mg(B_{1-x}C_x)_2 Single Crystals with x=0.132 from Point-Contact Spectroscopy
R. S. Gonnelli, D. Daghero, A. Calzolari +6
We report the results of the first directional point-contact measurements in Mg(B_{1-x}C_{x})_2 single crystals with 0.047 <= x <= 0.132. The two-gap superconductivity typical of M…
Point-Contact Spectroscopy in MgB_2: from Fundamental Physics to Thin-Film Characterization
R. S. Gonnelli, D. Daghero, A. Calzolari +9
In this paper we highlight the advantages of using point-contact spectroscopy (PCS) in multigap superconductors like MgB_2, both as a fundamental research tool and as a non-destruc…
The Magnetic-field Dependence of the Gaps in a Two-band Superconductor: A Point-contact Study of MgB_2 Single Crystals
R. S. Gonnelli, D. Daghero, A. Calzolari +6
We present the results of directional point-contact measurements in MgB_2 single crystals, in magnetic fields up to 9 T parallel to the c axis. By fitting the conductance curves of…
Directional point-contact spectroscopy of MgB2 single crystals in magnetic fields: two-band superconductivity and critical fields
R. S. Gonnelli, D. Daghero, G. A. Ummarino +6
The results of the first directional point-contact measurements in MgB2 single crystals, in the presence of magnetic fields up to 9 T either parallel or perpendicular to the ab pla…
