摘 要: 为提高YBa2Cu3O7-δ(YBCO)涂层导体的临界电流密度,使用无氟化学金属有机溶液沉积方法制备了YDyxBa2Cu3O7-δ薄膜,调研了薄膜的微观结构特征及超导电性。发现Dy元素的添加并没有得到预期的Dy2O3,没有有效提高YBCO的临界电流密度,却使超导薄膜成分发生偏析,从而导致其超导电性下降。
关 键 词: 超导物理学;YBa2Cu3O7-δ薄膜;Dy添加;有机溶液沉积

Abstract: For enhancing critical current density of YBa2Cu3O7-δ (YBCO) coating conductor, in this paper, YDyxBa2Cu3O7-δ films were prepared via a fluorine-free polymer-assisted metal organic deposition (PA-MOD) method. The microstructure and superconducting character of YBCO films were investigated. The results showed that there was no anticipative Dy2O3 in these films with the addition of Dy, and the critical current intensity was not increased efficiently. But the composition of YBCO occurred offseting, therefore the superconductivity capability of YBCO films degraded.
Key words: superconductivity physics; YBa2Cu3O7-δ films; Dy addition; polymer-assisted metal organic deposition
