A superconducting circuit having patterned superconducting wiring lines. Each wiring line consists of at least one portion (2') of the thin film (2) of an oxide superconductor deposited on a substrate (1). The portion (2') has a predetermined crystal orientation and the remaining portions (2") have a different crystal orientation or changed to non-superconductor. The superconducting circuit has a planar surface. In variations, two different wiring lines (21, 22) each having a different crystal orientation are produced at different portions of a thin film of oxide superconductor, so that superconducting current flow separately through two different portions in a common thin film.

L'invention est un circuit supraconducteur à configuration de conducteurs supraconducteurs. Chaque conducteur est constitué d'au moins une partie (2') de la couche mince (2) d'un oxyde supraconducteur déposé sur un substrat (1). La partie (2') a une orientation cristalline prédéterminée et les parties restantes (2") ont une orientation cristalline différente ou sont non-supraconductrices. Le circuit supraconducteur a une surface planar. Dans une variation de l'invention, deux conducteurs différents (21,22) ayant des orientations différentes sont produits dans des parties différentes d'une couche mince d'oxyde supraconducteur, de sorte que le courant circule séparément dans deux parties différentes d'une même couche mince.
