摘要:
A process for preparing an oxide crystal by means of solution growth in the presence of a solvent is provided. The solvent includes a mixture of an oxide containing at least one member of those elements which constitute the oxide crystal, a halide containing at least one member of those elements which constitute the oxide crystal, and metallic silver.

摘要:
An oxide superconductor comprises a base material (11) consisting of a single crystalline oxide, an oxide superconductor film (2B) consisting of a Y123 compound and formed on the single crystalline oxide base material (11), and a coating film (3) consisting of an oxide containing a Ba-Cu-O oxide as a main component and covering the surface of the oxide superconductor film (2B), the coating film (3) having a thermal expansion coefficient higher than that of the oxide superconductor film (2B).
