We report transport measurements on Superconductor/Ferromagnet/Superconductor (S/F/S) junctions: Nb/Al/Gd/Al/Nb where gadolinium (Gd) is a weakly polarized ferromagnet. A sizeable critical current I c is observed in the I(V) characteristics. This cur

Pour comprendre la supraconductivite a haute temperature critique, et tester les modeles theoriques proposes, l'effet tunnel et le couplage Josephson sont des outils tres importants. En mesurant la densite d'etats au niveau de Fermi d'une part, et le

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 conductance peak is observed in the tunneling conductance — which is

Summary Background Potentiation of the antitumor activity of 5-fluorouracil (5-FU) by folinic acid has been demonstrated in patients with colorectal adenocarcinoma. Modulation is due to the interaction of thymidylate synthase (TS), fluorodeoxyuridyla

Tunneling spectroscopy together with Josephson experiments give an interesting insight within the physics of High Temperature Superconductors. An incomplete gap is observed in the QP excitation spectrum, as if they were either states in the gap or no

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 irradiating a c-axis-oriented YBa2Cu3O7-? film through a gold mask such as th

The exchange-enhanced electron-electron interactions at the paramagnetic-ferromagnetic transition were studied experimentally via proximity effect tunneling spectroscopy. By solving the Usadel equations in both the paramagnetic and ferromagnetic stat

We have studied a new superconducting state where the condensate wave function resulting from conventional pairing, is modified by an exchange field. Superconductivity is induced into a ferromagnetic thin film (F) by the proximity effect with a super

We report on high-sensitivity measurements performed on weakly resistive Nb/Al/Gd/Al/Nb ferromagnetic rare-earth-based junctions. High interface barriers in such junctions can strongly modify interplay between ferromagnetism and superconductivity. We
