Abstract
The role of Ag in the enhancement of J(c) in YBa2Cu3O7-delta (YBCO) thin films is investigated. Studies show that the concentration of Ag in laser-ablated films made from YBCO targets containing 1-20 wt.% Ag, is less than 0.1%. J(c) has been found to improve with Ag doping by a factor of 8 in the films which were prepared from targets containing 5 wt.% Ag. A theoretical model based on the reduction in the resistive grain-boundary size is proposed to explain the observed enhancement of J(c).
