Abstract

We have investigated the effect of oxygen content on the c-axis transport in normal and mixed states on a Bi2Sr2CaCu2O8+x single crystal. The temperature dependence of normal state resistivity along the c axis is changed to be from semiconducting to metallic by annealing independently of the annealing atmosphere. In the mixed state, ρc(T, H) is found to be explained by the flux motion model. The fitting of ρc(T, H) with the form ρ = ρoexp[-Uo(T, H)/kBT] yields different magnetic field dependence of Uo for different oxygen content x. Some implications of these results are discussed.
