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…

Study of the Order Parameter symmetry in overdoped Y1-xCaxBa2Cu3O7-delta by measurement of Andreev reflection, evidence for enhancement of the sub dominant order parameter amplitude in high transparency contacts
A. Kohen, G. Deutscher
We have measured the differential Conductance of Au/Y1-xCaxBa2Cu3O7-delta point contacts in the regime where it is dominated by Andreev reflection, which enhances its value at low…
