Abstract

We report a ⁶³Cu and ¹⁷O NMR study in the high-T_c superconductor Tl₂Ba₂Ca₂Cu₃O₁₀ with T_c (max) = 127 K. The results of T₁ and T_2G reveal that the characteristic energy of the antiferromagnetic spin fluctuation Γ_Q is higher than that in YBa₂Cu₃O₇, while the magnetic correlation lengths ξ do not differ much from each other. The high T_c in this compound is thus related to large Γ_Q, suggesting that the superconductivity is spin fluctuation mediated.
