This study investigates the enhancement of current density in superconducting coated conductors of YBa₂Cu₃O₇₋ₓ (YBCO) films coated with BaZrO₃. The authors demonstrate a simple and industrially scalable method to improve magnetic flux pinning mechanisms, leading to a 1.5 to 5-fold increase in in-field current densities. The key findings include: 1. **Enhanced Pinning Mechanisms**: The addition of BaZrO₃ nanoparticles within YBCO films significantly improves critical current density (Jc) at 75.5K, both on single crystal and practical metallic substrates. 2. **Heteroepitaxial Growth**: BaZrO₃ nanoparticles grow heteroepitaxially within laser-ablated YBCO films, leading to increased dislocation density and improved pinning. 3. **Microstructural Analysis**: X-ray diffraction, atomic force microscopy, and transmission electron microscopy reveal the presence of nano-particles and dislocations in the YBCO+BaZrO₃ films, which contribute to enhanced pinning. 4. **Performance Improvements**: Despite slightly lower critical temperatures (Tc) compared to pure YBCO, the YBCO+BaZrO₃ samples show significantly higher Jc values over a wide magnetic field range, with a factor of 5 improvement at 7T. 5. **Angular Dependence**: The addition of BaZrO₃ results in a shift in the Jc peak along the c-axis, indicating strong pinning defects along this direction, which is crucial for practical applications. 6. **Conclusion**: The study shows that a straightforward and inexpensive target compositional modification can lead to substantial improvements in superconducting performance, making it a promising approach for enhancing the practicality of superconducting coated conductors.This study investigates the enhancement of current density in superconducting coated conductors of YBa₂Cu₃O₇₋ₓ (YBCO) films coated with BaZrO₃.
