本文报道了用激光沉积法在（１００）ＬａＡｌＯ３衬底上制备（Ｙ１－ｘＨｏｘ）Ｂａ２Ｃｕ３Ｏ７－δ（ｘ＝０，０．２，０．４）超导薄膜．结果表明，新超导薄膜表面光滑，具有很强的ｃ轴织构，零电阻温度Ｔｃ０约９１Ｋ，最佳临界电流密度Ｊｃ为４．７×１０６Ａ／ｃｍ２（７７Ｋ）．
This paper reports the preparation of (Y1-xHox) Ba2Cu3O7-δ (x = 0, 0.2, 0.4) superconducting thin films on (100) LaAlO3 substrates by laser deposition. The results show that the surface of the new superconducting thin film is smooth and has a strong c-axis texture. The zero-resistance temperature Tc0 is about 91K and the optimum critical current density Jc is 4.7 × 106A / cm2 (77K).
