Abstract

Temperature and field dependence of the critical current density J_cand its anisotropy in chemical vapor deposition processed (CVD) YBa₂Cu₃O₇films deposited on SrTiO₃(100) substrates were measured by a 4-probe resistive method. A kink in the temperature dependence of J_cwas found for B_c, while there was no kink in J_cfor Bl/c. This kink can be explained as the dimensional crossover effect from three-dimensional (3D) pinning to two-dimensional (2D) pinning. Below the temperature at which the kink appears, the 2D pinning affects the J_cproperties. The pinning model for 3D and 2D cases is explored, considering the extrinsic pinning and the intrinsic one, respectively.
