Abstract
In this paper, we report on the electrical resistivity of Bi2Sr2CaCu2O 8 single crystals, both in the ab-plane and along the c-axis. The samp les show metallic behaviour in both directions and an anisotropy ratio (rho(c)/rho(ab) approximate to 170 at room temperature) lower than wh at is currently known in the literature. Furthermore, zero resistance is obtained at 97 K, the highest T-c(0) reported so far for this compo und. We discuss these properties in terms of an interplane coupling th at would be stronger than what is normally obtained in this compound.
