Abstract

A method is disclosed for fabricating YBa2 Cu3 O7 superconductor layers with the capability of carrying large superconducting currents on a metallic tape (substrate) supplied with a biaxially textured oxide buffer layer. The method represents a simplification of previously established techniques and provides processing requirements compatible with scale-up to long wire (tape) lengths and high processing speeds. This simplification has been realized by employing the BaF2 method to grow a YBa2 Cu3 O7 film on a metallic substrate having a biaxially textured oxide buffer layer.
