Method of preparing oxide superconducting film

An oxide superconducting layer is formed on a base material of silver, whose single side is coated with MgO, or single-crystalline MgO for depositing a Bi2Sr2Ca2Cu3 phase in a crystallographically oriented state by sputtering, CVD or laser ablation, then metal lead or lead oxide is laid thereon by s...

Summary:An oxide superconducting layer is formed on a base material of silver, whose single side is coated with MgO, or single-crystalline MgO for depositing a Bi2Sr2Ca2Cu3 phase in a crystallographically oriented state by sputtering, CVD or laser ablation, then metal lead or lead oxide is laid thereon by sputtering to obtain a two-layer structure, and the two-layer structure is heat treated in the atmospheric air. Thus, a bismuth oxide superconducting film, which is excellent in crystal orientation as well as denseness and thereby being increased in critical current density, is formed on the base material.
