Abstract
A -NMR study was performed on a crystal in the metallic state using a beam of spin-polarized implanted at a mean depth of 90 nm. The spin-lattice relaxation rate is strongly influenced by the onset of incommensurate spin fluctuations. The nuclear relaxation rate can be explained using previously published bulk NMR and inelastic neutron spectroscopy measurements of the dynamic magnetic susceptibility to model the hyperfine coupling. A well-resolved quadrupolar-split NMR for implies a static stopping position in an interstitial site. The Knight shift is highly sensitive to the anisotropic static susceptibility.
