Abstract
A YBa2Cu3O7-δ (YBCO) film grown by metal organic decomposition (MOD) is a promising candidate in the realization of high-performance superconducting wires with high critical current density. Moreover, artificial pinning centers (APCs) inclusions improve the current transport performance of the films in both high magnetic fields and temperatures. YBCO films with and without artificial pinning centers were successfully obtained on single-crystal SrTiO3 (STO) by an environmental friendly low-fluorine coating solution approach. Percentages of 5% and 10% of BaZrO3 (BZO) are used as APCs. X-ray diffraction analyses have been performed to characterize the structural properties of the as-obtained structure. Current-voltage (I-V) characteristics have been collected at different magnetic fields to investigate the superconducting properties.
