Annealing Temperature Effects on and for Microwave Applications by TFA-MOD
(YBCO) superconducting films can be used for microwave applications due to their low surface resistance. Both and can be considered as applicable substrates since their excellent properties for the preparation of high-quality YBCO films and for the design of microwave elements. In order to optimize the annealing temperature, the microstructure and properties were investigated for and films prepared by trifluoroacetates metal organic deposition (TFA-MOD). The results show that the annealing temperature window is broader for YBCO films on substrates; while, thewindowisrelativenarrowerforYBCOfilmson substrates. The reasons were also discussed. The surface resistivity was measured for the samples with highest critical current density . The results will provide useful information about processing effects on YBCO films using TFA-MOD for microwave applications.
