Observation of Andreev bound states in YBaCuO/Au/Nb ramp-type Josephson junctions

B. Chesca, D. Doenitz, T. Dahm +6

We report on Josephson and quasiparticle tunneling in YBa2Cu3O7-x(YBCO)/Au/Nb ramp junctions of several geometries. Macroscopically, tunneling occurs in the ab-plane of YBCO either…
