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…

Scanning Tunneling Spectroscopy on the novel superconductor CaC6
N. Bergeal, V. Dubost, Y. Noat +7
We present scanning tunneling microscopy and spectroscopy of the newly discovered superconductor CaC. The tunneling conductance spectra, measured between 3 K and 15 K, show a c…

Direct test of pairing fluctuations in the pseudogap phase of underdoped cuprates
N. Bergeal, J. Lesueur, M. Aprili +3
We report on a direct test of pairing fluctuations in the pseudogap regime of underdoped superconducting cuprates using a Josephson junction. In this experiment, the coupling betwe…
