Abstract
The effects of iodine intercalation have been investigated for the Co-substituted Bi-2212 phase (Formula presented)(Formula presented)Ca((Formula presented)(Formula presented)(Formula presented)(Formula presented) with different δ values in the overdoped regime. Whereas in the pristine samples (Formula presented) depends on z and δ, in the intercalated ones (Formula presented) is independent of δ. This indicates that the hole concentration p in the Bi-2212 phase has an upper limit and becomes saturated by the transfer of holes from the intercalated iodine. (Formula presented)(z)/(Formula presented)(z=0) of the intercalated samples differs from that of the pristine ones. This suggests that the intercalation of iodine decreases (Formula presented) not only through an increase in p, but also through a structural change, probably the interlayer decoupling between adjacent blocks of the (Formula presented) planes.
