摘要：
Microwave properties of spin-cast YBa2Cu3O7-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 mOMEGA at 5.4 K and 3.1 mOMEGA 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.
