MOD方法制备Y0.5Yb0.5BCO薄膜及其性能研究
Growth and Property of Y0.5Yb0.5BCO Films Prepared by MOD Method
摘要
Abstract
Y0.5Yb0.5BCO film was successfully fabricated by fluorine-reduced metalorganic deposition (MOD)method through mixing the same concentrated YBCO and YbBCO precursor solution with 1:1 volume ratio. The film has strong (001) peaks and well biaxial texture. The surface of the film is dense without any cracks and pores.Besides, the elemental distribution is well-proportioned. It is found that the Yb elemental substitution improves the in-field properties effectively, especially at high fields, although it decreases the critical transition temperature (Tc)of the Y0.5Yb0.5BCO ftim. For example, the Jc value of Y0.5Yb0.5BCO film is as higher as 1.26 times than that of the pure YBCO film at 77K and 3T applied field. In order to further improve the property at lower field, 6mol% TaCl5 is added to Y0.5Yb0.5BCO precursor solution to obtain the Ta5+-doped Y0.5Yb0.5BCO film. The current carrying ability of the Ta5+-doped Y0.5Yb0.5BCO film is enhanced within the measured fields.关键词
