Subharmonic gap structures and Josephson effect in MgB2/Nb micro-constrictions
Filippo Giubileo, Marco Aprili, Fabrizio Bobba +3
Superconducting micro-constrictions between Nb tips and high quality MgB pellets have been realized by means of a point-contact inset, driven by a micrometric screw. Measurem…
Point-Contact Spectroscopy on RuSr2GdCu2O8
Samanta Piano, Fabrizio Bobba, Filippo Giubileo +2
We present Point-Contact experiments on polycrystalline RuSrGdCuO samples. The majority of tunneling curves shows a zero-bias conductance peak, which is modeled by assu…
Point Contact Study of the Superconducting Order Parameter in RuSr2GdCu2O8
Samanta Piano, Fabrizio Bobba, Filippo Giubileo +2
We have performed a detailed study of the conductance characteristics obtained by point contact junctions realized between a normal Pt/Ir tip and syntered RuSr2GdCu2O8 (Ru-1212) sa…
Two regimes in the magnetic field response of superconducting MgB
A. Kohen, F. Giubileo, Th. Proslier +10
Using Scanning Tunneling Microscope at low temperature we explore the superconducting phase diagram in the -band of the two-band superconductor MgB. In this band the peculia…
