On the knight shift of alloys

Abstract

Abstract The change and broadening of the Knight shift of silver produced by various solute element. are explained by the fluctuations in electronic density produced at long range by each solute atom. The change in Knight shift observed for Cd, In, Sn and Sb solutes are in satisfactory agreement with those computed using a free electrons approximation for the matrix. From the sign and the values of the changes observed for Pd and Pt solutes, it in concluded that most of the screening arises there from an emptying of their d shells especially for Pt. Finally the change and broadening of the Knight shift of the solute element. are explained in the same way.
