摘要：
To investigate the influence of spatial distributions of 3D pinning centers on critical current density J(c), BaZrO3-doped YBa2Cu3Oy thin films were fabricated by a quasi-multilayering process. The crossover from a random pinning feature to a peak behavior around the c-axis direction was observed in the angular dependence of J(c) when the thickness of a YBCO layer and the growth temperature were modulated. The positions of BaZrO3 particles within the films are considered to be more correlated in the c-axis direction as the thickness of a YBCO layer becomes thinner. The lower growth temperature, on the other hand, suppresses the migration of adatoms, leading to randomly distributed BaZrO3 particles. (C) 2012 Elsevier B.V. All rights reserved.
