抜粋

YBa2Cu3O7-x+BaZrO3+Y 2O3 (YBCO+BaZrO3+Y2O3) mixed films were prepared on SrTiO3/MgO substrates by pulsed-laser deposition, with an YBCO+BaZrO3 target with a thin Y 2O3 sector stuck on the top. The pinning properties for the double-doped YBCO+BaZrO3+Y2O3 thin film were enhanced in comparison with those of a pure YBCO sample prepared in the same experimental conditions. The maximum global pinning forces Fp for the double-doped sample are 12.8GN m-3 near 3 T at 77 K, 46.3 GN m-3 near 4 T at 65 K, and 122 GN m-3 near 9 T at 40 K. In the double-doped sample the angular dependence of Jc showed a broad peak at , due to the flux pinning by c-axis correlated defects, combined with a plateau, due to the flux pinning by isotropic pinning centers. Both BaZrO 3 nanorods parallel to the c-axis and Y2O3 nanoparticles randomly dispersed inside the YBCO matrix were consistently observed in the cross sectional transmission electron microscopy images.
