Original Paper


Sr2Nb2O7 (SNO)-doped Y0.5Gd0.5Ba2Cu3O7−x (YGBCO) and pure YGBCO thin films with pure c-axis orientation were prepared by pulsed laser deposition. Compared with a pure YGBCO film, T c and critical current density (J c) (77 K, 0 T) of the SNO-doped film decreased from 91.9 to 88.7 K and from 4.2 to 2.5 MA/cm2, respectively. SNO-doped YGBCO film exhibited significantly enhanced J c in a magnetic field up to 9 T at 4.2 K and up to 7 T at 65 K for B//C, indicating that the SNO-doped YGBCO film possessed more effective flux pinning centers, which were stacking faults, c-axis defects, and inclined defects identified by transmission electron microscopy analysis.
