R. Funahashi et al., EFFECT OF ELONGATION OF THE C-CELL DIMENSION ON INTRINSIC PINNING IN BI2SR2CACU2OX SINGLE-CRYSTALS, Applied physics letters, 64(5), 1994, pp. 646-648
A change of the intrinsic pinning strength by elongation of the c-cell
dimension in Bi2SrCaCu2Ox whiskers of single crystals has been studie
d by magnetic relaxation and irreversibility temperature (T-irr) measu
rements in the magnetic fields parallel to the a-axis. When the c-cell
dimension is elongated by annealing under a reduced pressure, the int
rinsic pinning strength is weakened. This result is consistent with an
intrinsic pinning model.
