Abstract

We find in the Bi2Sr2CaCu2O8+δ system that the characteristic temperatures Tχ* (below which the uniform susceptibilities χab(T] (H ⊥ c) and χc(T) (H ∥ c) decrease) and Tρc* (below which the out-of-plane resistivity ρc(T] shows typical upturn) coincide for all doping levels. We attribute the T dependence of χ's and ρc to the anomalous (pseudogapped) density-of-states (DOS) in high-Tc cuprates. In addition, an analysis of the anisotropy in the T dependence of χ's shows that the high-temperature component (dχ/dT < 0) is also caused by a DOS effect.
