摘要：

The normal-state in-plane resistivity rho(ab) and out-of-plane resistivity rho(c) are measured in La-doped Bi2Sr2CuOy (T-c similar or equal to 13 K) by suppressing superconductivity with 61 T pulsed magnetic fields. In the sample with the smallest rho(ab) (130 mu Omega cm at 100 K), metallic rho(ab) coexists with ''semiconducting'' rho(c) down to the lowest experimental temperature, 0.66 K (T/T-c = 0.05), evidencing the non-Fermi-liquid nature of Bi2Sr2CuOy.
