Abstract
The normal-state Hall coefficient and the in-plane resistivity are measured in La-doped K) single crystals and thin films by suppressing superconductivity with 61-T pulsed magnetic fields. In contrast to data above the below ∼10 K shows little temperature dependence in all the samples measured, irrespective of whether 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.
