Development of Superconducting Thin Films with a Critical Temperature Greater than 110K

Abstract

CSA provided superconducting thin films consisting of T12CalBa2Cu2ox on LaAl03. Films were generated using the pulsed laser deposition (PLD) method. The company achieved a zero resistance temperature of 115 deg K and a critical current density of 1,000,000 A/sq. cm. at 77 deg K. Relationships between the deposition process, the as-deposited film, annealing conditions, and the annealed film were investigated. Twenty thallium-based high temperature superconducting films on microwave compatible substrates were delivered under provisions of this contract.
