摘要:
In this paper, CeO2 buffer layer and YBCO superconducting layer were deposited on the yttrium stabilized zirconia (YSZ) single crystal by metal organic deposition (MOD) method. The values of Tc and Jc of the YBCO film were 90.5 K and 1.3 MA/cm2, respectively, it's indicated that high performance YBCO film was obtained. But BaCeO3 phase was found in YBCO/CeO2/YSZ film. Then, the formation condition of BaCeO3 and its influence on the superconducting performance of YBCO were investigated. The results revealed that BaCeO3 is formed after the synthesis of YBCO phase, and BaCeO3 is the product of the reaction between CeO2 and YBCO, and BaCeO3 phase is inevitable during the process of YBCO films by MOD method.
