· Journal of Low Temperature Physics
In-plane and out-of-plane resistivity and Hall coefficient measurements were carried out on Bi{sub 2.1{minus}x}Pb{sub x}Sr{sub 2}CaCu{sub 2}O{sub y} (x = 0 {approximately} 0.6) single crystals with various oxygen concentration. The resistivity anisotropy {gamma}{sup 2} (= {rho}{sub c}/({rho}{sub a} {rho}{sub b}){sup 1/2}) was decreased with an increase of oxygen concentration and Pb content. Hall coefficient, R{sub H}, measurement revealed that the Pb-doping increases carrier concentration in the present system, however, its essential effect on reducing anisotropy was confirmed by comparing R{sub H} and {gamma}{sup 2} of the Pb-free and Pb-doped crystals.
