Bean-Livingston barrier enhancement on nodal surface of the d-wave superconductor YBa2Cu3O{7-x}

G. Leibovitch, R. Beck, A. Kohen +1

Vortex entry into (110) oriented YBaCuO films has been studied by tunneling into Andreev - Saint-James bound states, whose energy is shifted by surface currents. At…

Probing the superconducting condensate on a nanometer scale

Th. Proslier, A. Kohen, Y. Noat +3

Superconductivity is a rare example of a quantum system in which the wavefunction has a macroscopic quantum effect, due to the unique condensate of electron pairs. The amplitude of…

Probing the superfluid velocity with a superconducting tip: the Doppler shift effect

A. Kohen, Th. Proslier, T. Cren +4

We address the question of probing the supercurrents in superconducting (SC) samples on a local scale by performing Scanning Tunneling Spectroscopy (STS) experiments with a SC tip.…

Superconducting vortex profile from fixed point measurements The Lazy Fisherman tunnelling microscopy method

A. Kohen, T. Cren, Th. Proslier +7

We introduce a mode of operation for studying the vortex phase in superconductors using scanning tunnelling microscopy (STM). While in the conventional STM method, the tip is scann…

Fabrication and characterization of scanning tunneling microscopy superconducting Nb tips having highly enhanced critical fields

A. Kohen, Y. Noat, T. Proslier +4

We report a simple method for the fabrication of Niobium superconducting (SC) tips for scanning tunnelling microscopy which allow atomic resolution. The tips, formed in-situ by the…
