Abstract

To elucidate the pseudogap phase diagram including the overdoped state of high transition temperature (high-Tc) cuprates, we must understand the origin of the positive out-of-plane magnetoconductivity observed in these compounds. For this purpose, the out-of-plane resistivity ρc(T,H) of an overdoped Bi1.6Pb0.4Sr2CaCu1.96Fe0.04O8+δ (Bi-2212) single crystal is measured under pulsed magnetic fields up to 60 T. We show that the superconducting density-of-states depletion effect, in addition to the pseudogap effect, clearly appears below the superconducting fluctuation regime, and the contribution becomes dominant in the superconducting state.
