Nuclear-magnetic-resonance studies of amorphous Ni-P alloys

Abstract
Measurements of NMR linewidth, Knight shifts, and relaxation time have been made on amorphous Ni-P alloys with phosphorous content between 15% and 25%. Alloys prepared by different techniques (electroplating and chemical deposition) give different Knight shifts, suggesting different local structures. Linewidth measurements support a binary dense random packing of hard-spheres model in which phosphorous atoms have only nickel neighbors.
