摘要：

The solute Knight shifts and nuclear spin-lattice-relaxation times of dilute solutions of Cu, Ga, In, Al, and Sb in silver and of Cu, Ga, In, and Al in gold have been investigated at 4.2°K. No marked concentration dependence was observed. Knight factors (electron density ratio between the solute atom in the alloy and the solute free atom) determined from both types of measurements show good agreement in magnitude and valence dependence. The exchange enhancement of the Korringa product is found to be larger for the silver than for the gold alloys. © 1969 The American Physical Society.
