Method for fabricating oxide superconducting wires by laser ablation

A method of fabricating an oxide superconducting wire using laser ablation of applying a laser beam onto a target containing components of an oxide superconductive material and depositing particles thereby scattered from said target on a heated long base material, said method comprising the steps of:

• arranging a mask between said target and said long base material for limiting a film forming region;
• feeding said long base material along its longitudinal direction to be passed through a film forming station provided therein with said target;
• applying said laser beam onto said target thereby scattering particles from said target by laser ablation under an oxygen pressure of at least 300 mTorr;
• and
• depositing said particles on said limited film forming region of said long base material for forming an oxide superconducting film.
