Epitaxial YBa2Cu3O7−x/BaZrO3films 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 (Jc) value (77 K, 0 T) of 6.0 MA/cm2. The enhancedJcderives from a high density of BZO nanoparticles existing in the YBCO matrix. With increasing BZO amount,Jcof the YBCO films begins to decrease due to larger particles.
