The 19F NMR spectra of YBa2Cu3OxFy have been obtained for several concentrations of x and y as a function of magnetic field and temperature above and below the superconducting transition temperature. The high gyromagnetic ratio of the 19F nucleus allows us to use relatively low resonance magnetic fields in the range 0.1-1.3T. This interval is a factor of 50 to 70 below previously reported NMR experiments. This bridges the gap between regions of low magnetic fields that were probed by μSR and high fields used in NMR experiments. We observe a linewidth dependence on the temperature and external magnetic fields. The results are interpreted in terms of different overlapping of the vortices.
