We studied the flux pinning properties of BaZrO₃-doped YBa ₂Cu₃O_7-x and BaSnO₃-doped YBa ₂Cu₃O_7-x films. We found that BaSnO ₃-doped films showed very high global pinning forces, F_p, of 28.3GNm^-3 (77K, ) and 103GNm^-3 (65K, ), twice that of BaZrO₃-doped films. Transmission electron microscopy analysis showed that, in both films, nanorods of the dopant phase were incorporated. The BaSnO₃ nanorods were nearly straight but the BaZrO₃ nanorods became curved with the increasing film thickness.
