摘要：

Superconductor films (25-125 mu m thick) were melt-grown under an elevated magnetic field (0-10 T). The degree of texture and transport critical current (J(c)) of these films were enhanced by the application of a magnetic field. J(c) increases with increasing magnetic field and the measured saturation magnetic field decreases with decreasing thickness of the film. This method provides for relatively rapid processing of highly textured Bi-2212/Ag thick film or tape. (C) 1999 Elsevier Science B.V. All rights reserved.
