Local tunneling probe of (110) Y_0.95Ca_0.05Ba_2Cu_3O_7-delta thin films in a magnetic field

J. H. Ngai, R. Beck, G. Leibovitch +2

Scanning tunneling spectroscopy was performed on (110)-oriented thin films of Ca-overdoped YCaBaCuO at 4.2K, to probe the local evolution of Andre…

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…

Field Induced Nodal Order Parameter in the Tunneling Spectrum of YBaCuO Superconductor

G. Leibovitch, R. Beck, Y. Dagan +2

We report planar tunneling measurements on thin films of YBaCuO at various doping levels under magnetic fields. By choosing a special setup configuration, we have p…

Transition from a mixed to a pure d-wave symmetry in superconducting optimally doped YBaCuO thin films under applied fields

G. Elhalel, R. Beck, G. Leibovitch +1

We have probed the Landau levels of nodal quasi-particles by tunneling along a nodal direction of (110) oriented YBaCuO thin films with a magnetic field applied per…

High Quality a-axis outgrowth on c-axis YlCa1-xBa2Cu3O7-d

Guy Leibovitch, Roy Beck, Guy Deutscher

The large amplitude of the high Tc (HTS) superconducting gap is attractive for improved electronic applications. However, the study of such HTS cuprates has uncovered that unlike t…

Determination of the critical current density in the d-wave superconductor YBCO under applied magnetic fields by nodal tunneling

Roy Beck, Guy Leibovitch, Alexander Milner +2

We have studied nodal tunneling into YBa2Cu3O7-x (YBCO) films under magnetic fields. The films' orientation was such that the CuO2 planes were perpendicular to the surface with the…
