The normal-state Hall coefficient R{sub H} and the in-plane resistivity {rho}{sub ab} are measured in La-doped Bi{sub 2}Sr{sub 2}CuO{sub y} (T{sub c}{approx_equal}13 K) single crystals and La{sub 2-x}Sr{sub x}CuO{sub 4} thin films by suppressing superconductivity with 61-T pulsed magnetic fields. In contrast to data above T{sub c}, the R{sub H} below {approximately}10 K shows little temperature dependence in all the samples measured, irrespective of whether {rho}{sub ab} exhibits insulating or metallic behavior. Thus, whatever physical mechanism gives rise to insulating behavior in the low-temperature normal state, it leaves the Hall conductivity relatively unchanged. {copyright} {ital 1997} {ital The American Physical Society}
