Abstract Low-temperature anisotropic normal-state resistivity is measured in La2−xSrxCuO4 single crystals by suppressing the superconductivity with a 61-T pulsed magnetic field. The logarithmic temperature dependence of both ϱab and ϱc first reported in Phys. Rev. Lett.75, 4662 (1995) is observed in a much cleaner x=0.08 sample, as well as in samples with x=0.15 which is near optimum doping, but slighly underdoped. This extension of the original observation suggests that the unusual insulating behavior is a generic property of the low-temperature normal-state of underdoped La2−xSrxCuO4 once superconductivity is suppressed.
