•We introduced holding temperature during crystallization process to control the size of BaZrO3 particles.•The YBCO film with small BaZrO3 particles was fabricated successfully by introducing holding temperature.•It was revealed that the in-field Jc was improved by introducing the holding temperature.
In this study, we investigated the correlation between microstructures and critical current density (Jc) of YBa2Cu3O7−X (YBCO) films with BaZrO3 (BZO) pinning centers by introducing holding temperature during the crystallization process. Smaller BZO particles and higher in-field Jc were found in the YBCO film with holding temperature than the one without. As a result, films with improved microstructures were successfully fabricated by implementation of additional process, holding temperature, and highly in-field Jc were obtained by introducing smaller BZO particles as artificial pinning centers.
