Nanoparticles should be strong artificial pinning centers in high-temperature superconducting films. We successfully used pulse laser deposition to introduce gold nanoparticles in REBa₂Cu₃O_7-δ (RE = Y, Gd) films. We used small angle X-ray scattering (SAXS) to obtain macroscopic information for the nanoparticles. SAXS showed that the average spacing and radius of the nanoparticles were 110-160 nm and 14-18 nm, respectively, which were consistent with the results from transmission electron microscopy. SAXS also suggested that the interface between the REBa₂Cu₃O_7-δ matrix and the nanoparticles is sharp. This indicated that gold nanoparticles could work as strong artificial pinning centers.
