Abstract

We have studied the ground state of the overdoped single-layered cuprate superconductor Bi2.1Sr1.9CuO6+δ (Tc = 8 K) by applying a strong magnetic field of 15.3 T to suppress superconductivity. In the normal state down to T = 1.6 K induced by the field, 63Cu nuclear spin-lattice relaxation rate (1/T1) is found to obey a T1T = const. relation, indicating that the ground state in the overdoped regime is a Fermi liquid state. Our result is at variance with a recent study by scanning tunneling microscopy (STM) that finds a pseudogap in a similar sample. The implication on the phase diagram is discussed.
