Abstract
We measure the magnetic-field dependence of the c-axis resistivity, ρ_c(H), in a series of Bi_{2}Sr_{2-x}La_xCuO_{6+δ} (BSLCO) single crystals for a wide range of doping using pulsed magnetic fields up to 58 T. The behavior of ρ_c(H) is examined in light of the recent determination of the upper critical field H_{c2} for this material using Nernst effect measurements. We find that the peak in ρ_c(H) shows up at a field H_p that is much lower than H_{c2} and there is no discernable feature in ρ_c(H) at H_{c2}. Intriguingly, H_p shows a doping dependence similar to that of T_c, and there is an approximate relation k_{B}T_c \simeq {1/2}gμ_{B}H_p. Moreover, we show that the data for the lowest-T_c sample can be used to estimate the pseudogap closing field H_{pg}, but the method to estimate H_{pg} proposed by Shibauchi {\it et al.} [Phys. Rev. Lett. {\bf 86}, 5763 (2001)] must be modified to apply to the BSLCO system.
