摘要：

A change of the intrinsic pinning strength by elongation of the c-cell dimension in Bi2SrCaCu2Ox whiskers of single crystals has been studied by magnetic relaxation and irreversibility temperature (T-irr) measurements in the magnetic fields parallel to the a-axis. When the c-cell dimension is elongated by annealing under a reduced pressure, the intrinsic pinning strength is weakened. This result is consistent with an intrinsic pinning model.
