Abstract

We report the results of ^63,65Cu-NMR measurements on single-layered copper-oxide Bi₂Sr_1.6La _0.4CuO_6+δ (T_c = 32 K) conducted under very high magnetic fields up to 45 T The high magnetic field suppresses superconductivity completely and the pseudogap ground state is revealed. The ⁶³Cu-NMR Knight shift shows that there remains a finite density of states at the Fermi level in the zero-temperature limit, which indicates that the pseudogap ground state is a metallic state with a finite volume of Fermi surface.
