摘要
PROBLEM TO BE SOLVED: To provide a method of manufacturing superconducting oxide thin film device by which a superconducting oxide thin film having a good c-axis orientation can be formed even when buffer layers are formed in thick layers.;SOLUTION: A thick CeO2 first buffer layer 2 contains a (111)-facet, and an Sm2O3 second buffer layer 4 caused to deposit on the first buffer layer 2 is grown as crystal grains smaller than CeO2 crystal grains by one figure or more. A thin EBCO film 5 is grown on the fine crystal grains. The superconducting thin film composed of such ideal crystal grains has a very high superconductive critial current density (Jc) as well as a very high superconductive critical temperature (Tce).;COPYRIGHT: (C)2005,JPO&NCIPI
