Abstract

⁶³Cu NQR measurement has been carried out in superconducting and nonsuperconducting (metallic) TlSr₂CaCu₂O_7-δ. In the superconducting material, 1/T₁ follows the T₁T=const. relation only in a narrow temperature range above T_c, 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.
