Effects of Film Thickness and Annealing Conditions on 2223 Phase Growth in BSCCO Films Produced by Pb Vapor Doping

Abstract
The conditions for increasing the fraction of the 2223 phase in BiSrCaCuO films in the Pb vapor doping method were investigated. The optimum range for the growth of the 2223 phase was determined as a function of annealing condition and film thickness. It is shown that the annealing at 835°C for 5 to 12 h after 850°C×3 h annealing in Pb atmosphere is most effective in obtaining the impurity-free 2223 phase. The fraction of the 2223 phase thus obtained exceeded 99%.
