Title:
FORMATION OF OXIDE SUPERCONDUCTING THIN FILM
Document Type and Number:
Japanese Patent JPH04231399
Kind Code:
A
Abstract:
PURPOSE:To obtain an oxide superconducting thin film having good C-axis orientation and intergranular matching, and consequently excellent in superconducting characteristics such as Jc. CONSTITUTION:An oxide superconducting thin film is formed on a substrate comprising a ceramic single crystal by vapor phase precipitation method. The precipitation surface of the substrate to be used is specified to such a plane inclining by 0.5-20 deg. from the specified crystal plane of the single crystal which constitute the substrate. Since the precipitation plane 1 inclining by 0.5-20 deg. angle has step-like crystal planes, these steps 3 fix the orientation of the a-b axis in the oxide superconductor when the oxide superconductive material is precipitated by vapor phase precipitation method, and thereby, good matching between grains in the substrate and superconductor can be obtd.
