ABSTRACT:
This invention provides a method for depositiing a superconducting thin film comprising at least one high temperature Bi-Sr-Ca-Cu-O-based superconductor phase onto a substrate such as, for example, a ceramic oxide or a metal. High temperature Bi-Sr-Ca-Cu-O-based superconductor phases include Bi.sub.2 Sr.sub.2 CaCu.sub.2 O.sub.8, Bi.sub.4 Sr.sub.3 Ca.sub.3 Cu.sub.4 O.sub.16, and Bi.sub.2 Sr.sub.2 Ca.sub.2 Cu.sub.3 O.sub.10.
