Trapped field and levitation force in melt-textured YBCO doped with Ni and Li

摘要

Trapped magnetic fields and levitation forces at 77 K have been studied in bulk melt-textured YBCO with single grains of 26 nun, doped with different content of Li and Ni. Li dopant results in higher trapped field than Ni indicating that Li additions are more effective in increasing pinning capabilities. (C) 2003 Elsevier Science B.V. All rights reserved.
