Observation of Periodic pi-Phase Shifts in Ferromagnet-Superconductor Multilayers
V. Shelukhin, A. Tsukernik, M. Karpovski +8
We report complementary studies of the critical temperature and the critical current in ferromagnet (Ni) - superconductor (Nb) multilayers. The observed oscillatory behavior of bot…
Luttinger liquid behavior in weakly disordered quantum wires
E. Levy, A. Tsukernik, M. Karpovski +6
We have measured the temperature dependence of the conductance in long V-groove quantum wires (QWRs) fabricated in GaAs/AlGaAs heterostructures. Our data is consistent with recent…
Proximity effect in granular superconductor-normal metal structures
I. Sternfeld, V. Shelukhin, A. Tsukernik +3
We fabricated three-dimensional disordered Pb-Cu granular structures, with various metal compositions. The typical grain size of both metals is smaller than the superconductor and…
Critical current in Nb-Cu-Nb junctions with non-ideal interfaces
Y. Blum, A. Tsukernik, M. Karpovski +1
We report on experimental studies of superconductor (Nb) - normal metal (Cu) - superconductor (Nb) junctions with dirty interfaces between the different materials. By using a set o…
