Liquid phase preparation of Bi-Sr-Ca-Cu-O film structures
Abstract
Textured Bi2Sr2CaCu2O(x) (BSCCO) films were grown from a solution-melt with 10-30 wt pct BSCCO and 70-90 wt pct KCl. The substrates were of YAlO3 of the orientation (110). The films consisted of crystallites of up to 300 microns in size ordered into grains and their c-axis was perpendicular to the substrate plane. The films had zero resistance at 82-85 K, and the critical current density was 100 A/sq cm at 77 K.
