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

The concentration dependence of nuclear spin-lattice relaxation time, T 1 , and the Knight shift of Al 27 and V 51 in Pb-Al and Pd-V alloys have been measured in the temperature range from 1.4 to 4.2 K. The measured T 1 T 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 T 1 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.
