Preparation of Bi-based Superconducting Thin Films by RF Magnetron Sputtering under Magnetic Field

Abstract

Crystallizations under magnetic field have being flourished. Using rf magnetron sputtering method under high magnetic field we formed Bi₂Sr₂Ca_n-1Cu_nO_y (Bi-based) superconducting thin films. Some of the deposited films showed zero resistance. Oxidization of films may be accelerated by applying magnetic field.
