ABSTRACT:
Josephson junctions have been formed from superconducting oxide ceramic materials. The tunnel juction is made from an oxide ceramic film which has a similar crystalline structure as said superconducting oxide ceramic. In light of the similarity of the crystalline structures, the good alignment is established between the superconducting ceramic and the barrier film and superconducting ceramic material having a high degree of crystallinity can be deposited on the barrier film with improved superconductive property.
