PCT No. PCT/GB95/00525 Sec. 371 Date Sep. 23, 1996 Sec. 102(e) Date Sep. 23, 1996 PCT Filed Mar. 10, 1995 PCT Pub. No. WO95/26575 PCT Pub. Date Oct. 5, 1995A superconductive junction (10) comprises a first track (22) of YBa2Cu3O7 surmounted by a second track (28) also of YBa2Cu3O7. An interconnect (26) in the form of a superconductive mesa electrically connects the first track to the second track and acts as a microbridge. When cooled below a critical temperature, the junction (10) shows Josephson-like behaviour. A non-superconductive layer (24) of PrBa2Cu3O7 separates the first track and the second track, with the interconnect extending through the PrBa2Cu3O7 layer in the form of an island. The junction (10) is fabricated by electron beam evaporation, optical lithography, and ion beam milling. |
