Abstract

We report a 63Cu and 17O NMR study in the high-Tc superconductor Tl2Ba2Ca2Cu3O10 with Tc (max) = 127 K. The results of T1 and T2G reveal that the characteristic energy of the antiferromagnetic spin fluctuation ΓQ is higher than that in YBa2Cu3O7, while the magnetic correlation lengths ξ do not differ much from each other. The high Tc in this compound is thus related to large ΓQ, suggesting that the superconductivity is spin fluctuation mediated.
