✦ Synopsis

lSR vortex data of YBa 2 Cu 3 O 7Àd (YBCO) are examined to determine the field dependence of antiferromagnetism (AF) in and near the vortex cores. Field distributions are obtained using maximum entropy. The vortex signal is best fitted by a Lorentzian indicating AF in and near the vortex cores. The field dependence of the YBCO AF Lorentzian linewidth qualitatively agrees with theoretical predictions.
