Nuclear Magnetic Resonance in Palladium-Aluminum and Palladium-Vanadium Alloys

Abstract

The concentration dependence of nuclear spin-lattice relaxation time, T₁, and the Knight shift of Al²⁷ and V⁵¹ in Pb–Al and Pd–V alloys have been measured in the temperature range from 1.4 to 4.2 K. The measured T₁T and the Knight shift of impurities in diluted Pd–Al and Pd–V alloys are 24.8±3.0 sec K, −0.002±0.005% and 3.0±0.2 sec K, +0.75±0.02%, respectively.
A consistent explanation for the electronic state in the impurity site is given using the results of T₁ and the Knight shift. Especially, the results in the dilute Al alloys are discussed with the recent Kanamori-Terakura theory which has been established for ferromagnetic Ni alloys.
