Abstract
We have measured 63,65Cu NMR/NQR spectra, 199Hg and 19F NMR spectra and spin-lattice relaxation rate on a series of powder HgBa 2CuO 4+ x F y samples with different oxygen and fluorine content. Comparison of 63Cu and 199Hg relaxation data to numerical calculations for several types of the order parameter symmetry gives the best coincidence with the d-wave symmetry. 19F NMR line width and relaxation rate are strongly influenced by the magnetic flux-line motion. The 19F magnetization recovery curve is described by a stretched exponential function. The 19F spin-lattice relaxation strongly depends on the fluorine content evidencing that at higher doping level part of F atoms occupy the apical O2 position.
