High Tc Josephson nanoJunctions made by ion irradiation : characteristics and reproducibility
Jerome Lesueur, Nicolas Bergeal, Martin Sirena +4
Reproducible High Tc Josephson junctions have been made in a rather simple two-step process using ion irradiation. A microbridge 1 to 5 micrometers wide is firstly designed by ion…
High-Quality Planar high-Tc Josephson Junctions
N. Bergeal, X. Grison, J. Lesueur +3
Reproducible high-Tc Josephson junctions have been made in a rather simple two-step process using ion irradiation. A microbridge (1 to 5 ?m wide) is firstly designed by ion irradia…
Oscillations of the superconducting order parameter in a ferromagnet
T. Kontos, M. Aprili, J. Lesueur +1
Planar tunneling spectroscopy reveals damped oscillations of the superconducting order parameter induced into a ferromagnetic thin film by the proximity effect. The oscillations ar…
Andreev Bound States and Josephson Coupling in YBCO/Pb tunnel junction
J. Lesueur, X. Grison, M. Aprili +1
We have made in-situ [103] and [110]YBCO/Pb junctions, which display an hysteretic behaviour with both a well-defined Quasi-Particule branch and a Josephson current. A zero energy…
Enhancement of Andreev reflection by spin polarization in out-of-equilibrium ferromagnet-superconductor junctions
O. Bourgeois, P. Gandit, J. Lesueur +4
We report on transport measurements on Nb/Al/Gd/Al/Nb junctions.Bulk Gadolinium is a weakly polarized ferromagnet (5-7%), and is present in the junction in granular form (superpara…
