Abstract:
1. A method for joining an RE123 oxide superconductor produced by a melt process, comprising: aligning a plane to be joined of an RE123 oxide superconductor so as to be parallel to the (110) crystallographic plane; interposing a solder material composed of an RE123 oxide superconductor material having a lower melting point than the RE123 oxide superconductor between the planes to be joined; and melting and then solidifying said solder material to form a joining layer, wherein RE is one or more members selected from the group consisting of Y, La, Pr, Nd, Sm, Eu, Gd, Dy, Ho, Er, Tm, Yb and Lu.
