YBa2Cu3Oy (YBCO) films with BaHfO3 (BHO) nanoparticles were fabricated by a metal organic deposition (MOD) method using a solution with trifluoroacetates and Hf salts. X-ray diffraction (XRD) revealed the formation of BHO in highly oriented YBCO film, and scanning transmission electron microscopy (STEM) with energy dispersive X-ray spectroscopy (EDS) showed the elemental distributions of Y, Cu, Ba, Hf and O in the film. The average size of BHO in the film was about 18 nm. Critical current density (Jc) properties of the films with BHO were higher than those of the films with BaZrO3 in magnetic fields.
