Abstract

The room temperature nuclear magnetic resonance (NMR) spectrum of Ag109 in nanophase silver is presented. In contrast to previous measurements of Cu in nanophase copper, where evidence of a significant distribution of anisotropic Knight shifts is present, the Ag signal can be understood in terms of a distribution of isotropic Knight shift. The width and shape of the response can be interpreted using a simple model for the grain boundary resulting in spatial variations in the electron wavefunction within the material. © 1993.
