Abstract

Microwave properties of spin-cast YBa₂Cu₃O _7-x thin films on LaAlO₃ substrates were investigated. The films, prepared with carboxylate solution precursors and by reactive liquid phase sintering mechanism, showed dense epitaxial structure and good electrical properties. The surface resistance, measured at a frequency of 10 GHz, was 0.47 mΩ at 5.4 K and 3.1 mΩ at 77 K. The results indicate that this technique can be used to fabricate superconducting thin films for microwave applications at low cost and with wide area coverage.
