Abstract
We study DC magnetization, electrical conductivity and AC susceptibili ty of Bi(2212) single crystals before and after iodine intercalation. The position of the magnetic irreversibility line in the (B-T) plane r emains virtually unchanged upon I intercalation, indicating that the d imensionality of the flux-line lattice does not change. We attribute t he observed strong decrease of the resistivity ratio rho(c)/rho(ab) af ter the intercalation to an extrinsic, defect-mediated conductivity me chanism along the c-axis.
