Abstract
A large superconductor intermediate of REBa Cu O system (where RE is one kind or a combination of rare earth elements including Y), characterized by a structure that oxide superconductors having non-superconductive phases finely dispersed in REBa Cu O phases (123 phases) of different peritectic temperatures (Tp) are laminated three-dimensionally in the order of Tp's, seed crystals mounted on the oxide superconductor layer having a highest Tp, and excluded phases included in at least the oxide superconductor having the high Tp.
