Abstract
Spatially-resolved NMR is used to probe antiferromagnetism in the vortex state of nearly optimally doped high-Tc cuprate Tl2Ba2CuO6+δ (Tc = 85 K). The broadened 205Tl-spectra below 20 K and the temperature dependence of the enhanced nuclear spin-lattice relaxation rate 205T1−1 at the vortex core region indicate clear evidences of the antiferromagnetic order inside the vortex core of Tl2Ba2CuO6+δ.
