Abstract

63Cu NQR measurement has been carried out in superconducting and nonsuperconducting (metallic) TlSr2CaCu2O7-δ. In the superconducting material, 1/T1 follows the T1T=const. relation only in a narrow temperature range above Tc, suggesting the existence of the AF spin fluctuation. The reduction of 1/T1T observation the non-superconducting sample suggests that the suppression of the spin fluctuation by the overdoped hole destroys the superconductivity.
