Abstract

NMR measurements of the linewidth of planar 17O in near-optimally doped YBa2Cu3O7-δ in the vortex lattice state are reported. We find that the lineshape, i.e. magnetic field probability distribution, is much broader than what is expected based on the calculated distribution arising from the vortex supercurrents. We can qualitatively account for this anomalously large NMR linewidth measured at low temperatures by postulating that the broadening is caused by antiferromagnetism in the vortex core.
