The normal-state in-plane resistivity {rho}{sub {ital ab}} and out-of-plane resistivity {rho}{sub {ital c}} are measured in La-doped Bi{sub 2}Sr{sub 2}CuO{sub {ital y}} ({ital T}{sub {ital c}}{approx_equal}13 K) by suppressing superconductivity with 61 T pulsed magnetic fields. In the sample with the smallest {rho}{sub {ital ab}} (130 {mu}{Omega} cm at 100 K), metallic {rho}{sub {ital ab}} coexists with {open_quote}{open_quote}semiconducting{close_quote}{close_quote} {rho}{sub {ital c}} down to the lowest experimental temperature, 0.66 K ({ital T}/{ital T}{sub {ital c}}=0.05), evidencing the non- Fermi-liquid nature of Bi{sub 2}Sr{sub 2}CuO{sub {ital y}}. {copyright} {ital 1996 The American Physical Society.}
