Andreev reflection in Au/La_{2-x}Sr_{x}CuO_{4} point-contact junctions: separation between pseudogap and phase-coherence gap
R. S. Gonnelli, A. Calzolari, D. Daghero +4
We made point-contact measurements with Au tips on La_{2-x}Sr_{x}CuO_{4} samples with 0.08 < x < 0.20 to investigate the relationship between superconducting gap and pseudogap. We…
Temperature and junction-type dependency of Andreev reflection in MgB2
R. S. Gonnelli, A. Calzolari, D. Daghero +6
We studied the voltage and temperature dependency of the dynamic conductance of normal metal-MgB2 junctions obtained either with the point-contact technique (with Au and Pt tips) o…
Josephson effect in MgB_2 break junctions
R. S. Gonnelli, A. Calzolari, D. Daghero +5
We present the first observation of the DC and AC Josephson effect in MgB_2 break junctions. The junctions, obtained at 4.2 K in high-quality, high-density polycrystalline metallic…
