Systematic effects of Zr additions on the structural and flux pinning properties of YBa 2 Cu 3 O 7−δ (YBCO) films deposited by metal–organic chemical vapor deposition (MOCVD) have been investigated. Detailed characterization, conducted by coordinated transport, x-ray diffraction, scanning and transmission electron microscopy analyses, and imaging Raman microscopy have revealed trends in the resulting property/performance correlations of these films with respect to varying mole percentages (mol%) of added Zr. For compositions ≤7.5 mol%, Zr additions lead to improved in-field critical current density, as well as extra correlated pinning along the c -axis direction of the YBCO films via the formation of columnar, self-assembled stacks of BaZrO 3 nanodots.
