Title: Electron-Mediated O[number sign]17-C[number sign]63u Spin-Spin Coupling and Electron Spin Correlations in YBa[sub 2]Cu[sub 3]O[sub 7]

Abstract

We report spin-echo double resonance NMR measurements of [sup 17]O- [sup 63] Cu indirect (electron-mediated) nuclear spin-spin coupling between Cu and O atoms in the CuO[sub 2] planes of YBa[sub 2]Cu [sub 3]O[sub 7] . The magnitude of the measured coupling is anomalously large, to the extent that it is inconsistent with the antiferromagnetic correlations that are invoked to explain the contrasting T[sub 1] behaviors of [sup 63]Cu and [sup 17]O .
