Abstract

We report on the critical current properties of the BaZrO3(BZO)- and Co-doped ErBa2Cu3Oy thin films grown by the pulse laser deposition method. The BZO-doped Er123 films processed through the oxygen post-annealing showed clear enhancement of critical current density (Jc) in comparison with normal Er123 thin films. Even in the BZO doping level of 0.5 wt.% for Er123, TEM observation revealed that nano-rods of BZO were embedded in Er123 matrix, which was qualitatively consistent with a result of angular dependence of Jc at 77 K. The Tc values of the slightly Co-doped films depend on the substrate temperature, while irreversibility lines for the temperature normalized by Tc were almost coincident with one another, which were overlapped on that of the normal Er123 thin film. The positive Co-doping effect on Jc emerged at low temperatures. We believe that local regions with lower Tc, in which the Co doping levels in the CuO2 planes were relatively higher than that of matrix, act as vortex pinning centers.
