概要
- 論文の詳細を見る
The superconducting oxide Y-Ba-Cu-O has successfully been fabricated by the sol-gel method using Y, Ba, and Cu alkoxides as starting materials. Powders with specific surface area of 15 m^2/g are prepared by this method. An X-ray diffraction pattern attributed to a 1-2-3 structure appears at 750℃and a bulk sample with T_c of 90 K is made by 900℃sintering in an oxygen atmosphere. A film of T_c=80 K with c-axis orientation is also fabricated using the sol-gel paste on an yttrium-stabilized ZrO_2 substrate.
