Outline of Final Research Achievements

We have successfully fabricated 5 mol% Zr-doped superconducting thin films with improved critical current density in magnetic fields by chemical engineering technique using metal-organic deposition without fluorine-free splitting and thermal treatment with double steps. BaZrO3 nanoparticles were confirmed in the Zr-doped superconducting films by high-resolution transmission electro microscopy. The GdBCO films with mixed Rare earth elements such as Eu, Dy, Sm, Ho showed improved Jc-B properties compared to the pure films. 5-mol%-Ho-doped GdBCO films also showed high Jc-B performance.
