ABSTRACT:
A process for producing a freestanding high Tc superconducting thin film is disclosed, which comprises providing a carbon substrate, depositing a high Tc superconducting thin film on the substrate and removing the carbon substrate by converting the carbon substrate to a gaseous composition at a temperature insufficient to cause thermal damage to said superconducting thin film but greater then 500.degree. C. in an oxygen containing atmosphere.
