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 7mol% BZO have a maximum critical current density (J c) value (77K, 0T) of 6.0MA/cm2. 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.
