METHOD FOR MANUFACTURING TRIAXIAL ORIENTATION OXIDE SUPERCONDUCTING COMPLEX AND TRIAXIAL ORIENTATION BISMUTH OXIDE SUPERCONDUCTING COMPLEX

摘要

PROBLEM TO BE SOLVED: To realize a triaxially oriented organization of oxide superconducting complexes, having an excellent critical current density, by employing a remarkably simple process.;SOLUTION: A composite comprising a precursor and a substrate of an oxide superconductor is baked in a furnace with a temperature gradient of 0.5-10°C/cm, allowing at least one part of the precursor to melt. Thereafter, the composite is slowly cooled and solidified with the above temperature gradient being maintained, and transformed into a triaxial orientation oxide superconductor having a triaxially oriented organization.;COPYRIGHT: (C)2001,JPO
