Abstract
We report Y-89 and O-17 NMR (9 Tesla) spin echo decay (T-2) measuremen ts for YBa2CU3O7 We correct the results to remove effects of (CU)-C-63 ,65 dipolar coupling in order to isolate effects of vortex dynamics. W e confirm vortex localization in the vortex solid state with rms displ acements consistent with Langevin dynamical theory, but with motional dynamics at time scales some 10(6) times slower than predicted.
