    Observation of Tomasch oscillations and tunneling-like behavior in oxygen-deficient edge junctions (1999)

    Notes: Properties of oxygen-deficient edge junctions made of YBa2Cu3O6.6 as the superconductor and YBa2Cu3−xFexOy as the barrier are reported. These junctions show weak-link characteristics when the edge angle is 50°, while tunneling-like behavior is observed when the edge angle is 36°. In all junctions strong peaks in the conductivity are found, which depend on the specific junction geometry. Some series of peaks were identified as due to Tomasch oscillations in the cover electrode, which yield Δ=1.4±0.2 meV and vF′=(4.4±0.2)×107 cm/s. © 1999 American Institute of Physics.

    Proximity effect in bilayer films of YBa2Cu2.7Fe0.3Oy and YBa2Cu3O7−δ (1998)
    Woodbury, NY : American Institute of Physics (AIP)

    Notes: We studied the proximity effect in a series of YBa2Cu2.7Fe0.3Oy/YBa2Cu3O7−δ bilayer film with varying YBa2Cu3O7−δ thickness. In a bilayer of isolated YBCO islands, a Tc of 72 K was observed, much higher than Tc of 32 K of the YBa2Cu2.7Fe0.3Oy film. Tc and Jc of thicker bilayers of continuous YBa2Cu3O7−δ films were found to decrease with decreasing YBCO thickness. This behavior of Tc and Jc can be explained by the Deutscher de Gennes theory for the proximity effect, provided one models the film as a series of grains whose lateral dimensions scale with the average film thickness. © 1998 American Institute of Physics.

    Retrieval of critical current distribution in small Josephson junctions (1997)
    Woodbury, NY : American Institute of Physics (AIP)

    Notes: We have developed a method to retrieve or to estimate the spatial critical current distribution in a small Josephson junction from a critical current measurement in a magnetic field (the junction size is in reference to the Josephson length). The method is based on an iterative algorithm that uses fast Fourier transform and physical constraints to achieve the proper solution(s). We simulated some typical critical current distributions and the algorithm converged to a single solution. We applied the algorithm to measurements of the critical current of grain boundary junctions of an oxygen deficient YBa2Cu3O7−δ thin film. The convergence was always to one of a very few solutions very similar in nature. © 1997 American Institute of Physics.
