Abstract
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.
