Independent determination of the two gaps by directional point-contact spectroscopy in MgB_2 single crystals
R. S. Gonnelli, D. Daghero, G. A. Ummarino +4
Directional point-contact spectroscopy measurements were performed for the first time in state-of-the-art MgB_2 single crystals. The selective suppression of the superconductivity…

Direct evidence for two-band superconductivity in MgB_2 single crystals from directional point-contact spectroscopy in magnetic fields
R. S. Gonnelli, D. Daghero, G. A. Ummarino +4
We present the results of the first directional point-contact spectroscopy experiments in high-quality MgB_2 single crystals. Due to the directionality of the current injection int…
