摘要：

The demand for coated conductors with high cost performance has triggered the search for effective artificial pinning centers by the low cost and high-scalability route. In this work, YBa2Cu3O7-x (YBCO) nanocomposite films with BaMnO3 nanosized particles induced by manganese (Mn) addition were prepared by low-fluorine metal-organic deposition. A strategy of rapid heating during the medium-temperature stage was adopted to reduce the size of the BaMnO3 nanoparticles and improve the quality of the YBCO films An enhanced critical current density and pinning force were found in the high-quality YBCO film embedded with extraordinarily small nanoparticles (average 3 +/- 1 nm).
