摘要：

The low-temperature normal-state resistivities of underdoped La2-xSrxCuO4 crystals with T-c of 20 and 35 K were studied by suppressing the superconductivity with pulsed magnetic fields of 61 T. Both in-plane resistivity rho(ab) and out-of-plane resistivity rho(c) are found to diverge logarithmically as T/T-c --> 0. Logarithmic divergence is accompanied by a nearly constant anisotropy ratio, rho(c)/rho(ab), suggesting an unusual three-dimensional insulator.
