摘要：
We report spatially resolved nuclear-magnetic-resonance measurements on a high-temperature superconductor that indicate the presence of correlated antiferromagnetic fluctuations in the vortex core. The nuclear-spin-lattice relaxation rate 1/T-17(1) of planar O-17, in near-optimally doped YB2Cu3O7-delta, was measured. Outside of the core, ((T1T)-T-17)(-1) is independent of temperature consistent with theoretical predictions for a d-wave superconductor. In the vortex core, ((T1T)-T-17)(-1) increases with decreasing temperature following an antiferromagnetic Curie-Weiss law.
