室温下应用Ａｒ＋ 离子源辅助准分子脉冲激光沉积（００２）取向的ＹＳＺ（Ｙｔｔｒｉａ－ｓｔａｂｉｌｉｚｅｄ ｚｉｒｃｏ－ｎｉａ）过渡层薄膜于不锈钢基底上；基底加温至７５０℃，用准分子脉冲激光沉积高电流密度ＹＢＣＯ（ＹＢａ２Ｃｕ３Ｏ７－ ｘ） 高温超导线材。实验结果表明：ＹＢＣＯ 超导线材临界温度Ｔｃ ≥９０ Ｋ （Ｒ＝０），临界电流密度Ｊｃ ≥１×１０６ Ａ／ｃｍ ２（７７ Ｋ，０ Ｔ）。

The (002) directional Yttria Stabilized Zirconia (YSZ) buffered layer film was deposited on the stainless steel substrate with the Ar + ion beam assistence at room temperature,and then the  YBa 2Cu 3O 7-x  (YBCO) film was deposited on the YSZ/stainless steel substrate at 750℃ by pulsed laser ablation. The experimental results show that the critical temperature and the critical current density of the YBCO superconducting film are 91 K ...
