A thin film of oxide superconductor possessing locally different crystal orientations and a process for preparing the same.

摘要

A thin film of oxide superconductor comprising first portions (10) consisting of an a-axis oriented thin film of oxide superconductor and second portions (11,12) consisting of a c-axis oriented thin film of oxide superconductor. The first portions (10) are deposited on an a-axis oriented very thin under-film layer (100) of oxide superconductor which is deposited previously on said substrate (2) while said second portions (11, 12) are deposited directly on said substrate (2). The differently oriented portions (10; 11, 12) of thin film of oxide superconductor are juxtaposed on said substrate (2).
