Abstract

Epitaxial YBa ₂Cu ₃O _7-x /BaZrO ₃ 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 BaZrO ₃ (BZO) on the structure and properties of YBa ₂Cu ₃O _7-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.
