Abstract

YBCO films with BaHfO3 (BHO) nanoparticles were fabricated by a metal organic deposition method using trifluoroacetate (TFA) solution with Hf salt. The diameter of BHO nanoparticles was minimized by the additional holding temperature during the crystallization process. Critical current density (JC) in magnetic fields of YBCO films with BHO nanoparticles was higher than that of the film with BaZrO3 (BZO). Accordingly, it was revealed that BHO nanoparticles act as very effective artificial pinning centers.
