Abstract (en)

[origin: WO9114028A1] High temperature superconducting layered structures for use in microwave applications are fabricated by depositing a thin film of epitaxial buffer (14) such as strontium titanate or calcium titanate by a deposition process such as laser ablation on a low loss sapphire substrate (12) followed by depositing an in-situ grown film of high temperature superconductor (16) such as Y1Ba2Cu3O7 on the buffer layer. The YBCO film has low surface resistance and a narrow transition temperature.
