Abstract :

In this study we have fabricated YBa₂Cu₃O_7-x (YBCO)/PrBa₂Cu₃O_7-x (PBCO)/YBCO multi-layer wiring and investigated its properties. We found that a polishing technique is extremely effective in the elimination of precipitates on the films without degradation in film properties. YBCO/polished-PBCO/polished-YBCO crossover with 50 μm square of overlap showed resistance of a degree of kΩ at 4.2 K while a contact of two YBCO layers through a 10 μm square of hole in the PBCO layer exhibited good superconductivity.
