We find in the Bi2Sr2CaCu2O8+δ system that the characteristic temperatures T*χ (below which the uniform susceptibilities χab(T) (H ⊥ c) and χc(T) (H ‖ c) decrease) and T*ρc (below which the out-of-plane resistivity ρc(T) shows typical upturn) coincidence 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. Furthermore, the anisotropy in the T dependence of χ’s is universal, i.e., χc ∝ 1.6χab, showing that there is only a single T-dependent component in the χ’s. This implies that the Curie-like behavior (dχ/dT) observed in overdoped samples is also caused by a DOS effect.
