摘要：

We report the temperature dependence of the q-dependent static electron spin susceptibility chi'(q) in a high-T(c) superconductor YBa2Cu3O6.9 obtained by measuring the Gaussian component of Cu-63 nuclear spin-spin relaxation rate 1/T2G. We employ the low-field NMR technique, and explain why this difficult technique is necessary for obtaining reliable results. It was found that chi'(q) satisfies a Curie-Weiss law at the corner of the Brillouin zone above T(c). Comparison with the spin-lattice relaxation rate 1/T1 showed little evidence for pseudogap behavior.
