Critical Current Density and Coupling Nature of Grains in Textured Bi(Pb)-Sr-Ca-Cu-O Superconductors

Abstract
The J c-H property of Bi-Sr-Ca-Cu-O tape was improved by a combination of the doctor blade and cold working preparation processes. A.C. complex susceptibility measurement indicates that this improved property is attributable to the improvement in the intergrain coupling along the current direction due to the grain orientation alignment in the tape.
