摘要：
After-treatment of a compound oxide type superconducting material by oxygen plasma to improve the superconducting property of the material. The treatment by oxygen plasma is preferably performed while the material is heated at 500 to 1,000 °C.
The material may have a form of bulky mass or of a thin film deposited on a substrate by physical vapour deposition technique.
