Preparation of superconducting films and a process for preparing the films

摘要

A novel ceramic substrate useful for the preparation of superconducting films, said substrate having the formula REBa2MO6 where RE represents rare earth metals-Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu and M represents metals Nb, Sb, Sn, Hf, Zr; and a process for the preparation of superconducting YBa2Cu3O7- delta thick films on new ceramic substrate.
