ABSTRACT:
A superconductive device and method for the manufacture thereof is disclosed, having a tunneling Josephson element comprising a first oxide superconductor electrode, a blocking layer consisting of a metal substantially inert to oxygen formed on the surface of the oxide superconductor, an insulating thin film layer formed on the blocking layer, and a second superconductor electrode opposing said first electrode formed on the insulating thin film.
