摘要
Epitaxial YBa2Cu3O7-x /BaZrO3 films were prepared by complex metal-organic solutions including Y, Ba and Cu anhydrous trifluoroacetate precursors and Zr acetylacetonate precursors. The influence of the amount of BaZrO3 (BZO) on the structure and properties of YBa2Cu3O7-x (YBCO) films was systematically investigated. The YBCO films having 7 mol % BZO have a maximum critical current density (J (c)) value (77 K, 0 T) of 6.0 MA/cm(2). The enhanced J (c) derives from a high density of BZO nanoparticles existing in the YBCO matrix. With increasing BZO amount, J (c) of the YBCO films begins to decrease due to larger particles.
