摘要：

63Cu NMR in Tl2Ba2CuO6−y with Tc = 90 K and 10 K has been investigated. The nuclear spin lattice relaxation rate, 1/T1 of 63Cu is found for the first time to follow a T1·T=const.law in a wide temperature range above Tc being strongly enhanced by the on-site coulomb correlation. This behavior of 1/T1 implies that the Fermi liquid picture is applicable to explore the mechanism of the high-Tc superconductivity. © 1990, Elsevier Science Publishers B.V. (North-Holland).
