High efficiency deterministic Josephson Vortex Ratchet
M. Beck, E. Goldobin, M. Neuhaus +3
We investigate experimentally a Josephson vortex ratchet -- a fluxon in an asymmetric periodic potential driven by a deterministic force with zero time average. The highly asymmetr…
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…
Non-ideal artificial phase discontinuity in long Josephson 0-kappa-junctions
T. Gaber, E. Goldobin, A. Sterck +4
We investigate the creation of an arbitrary -discontinuity of the Josephson phase in a long Nb-AlO_x-Nb Josephson junction (LJJ) using a pair of tiny current injectors, and stud…
Microscopic Analysis of Low-Frequency Flux Noise in YBaCuO Direct Current Superconducting Quantum Interference Devices
D. Doenitz, R. Straub, R. Kleiner +1
We use low-temperature scanning electron microscopy combined with SQUID detection of magnetic flux to image vortices and to investigate low-frequency flux noise in YBaCuO$_…
Ground states of one and two fractional vortices in long Josephson 0-kappa-junctions
E. Goldobin, D. Koelle, R. Kleiner
Half integer Josephson vortices in 0--junctions, discussed theoretically and observed experimentally, spontaneously appear at the point where the Josephson phase is -disconti…
Fluxon-semifluxon interaction in an annular long Josephson 0-pi-junction
E. Goldobin, N. Stefanakis, D. Koelle +1
We investigate theoretically the interaction between integer and half-integer Josephson vortices (fluxons and semifluxons) in an annular Josephson junction. Semifluxons usually app…
