摘要：

The normal-state Hall coefficient R-H and the in-plane resistivity rho(ab) are measured in La-doped Bi2Sr2CuOy (T-c similar or equal to 13 K) single crystals and La2-xSrxCuO4 thin films by suppressing superconductivity with 61-T pulsed magnetic fields. In contrast to data above T-c, the R-H below similar to 10 K shows little temperature dependence in all the samples measured, irrespective of whether rho(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.
