Py. Chu et al., MICROWAVE SURFACE-RESISTANCE OF SPIN-CAST YBA2CU3O7-X THIN-FILMS ON LAALO3 SUBSTRATES, Applied physics letters, 63(25), 1993, pp. 3512-3514
Microwave properties of spin-cast YBa2Cu3O7-x thin films on LaAlO3 sub
strates were investigated. The films, prepared with carboxylate soluti
on 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 ca
n be used to fabricate superconducting thin films for microwave applic
ations at low cost and with wide area coverage.
