The resistivity of liquid alloys

Abstract

The theory of the resistivity of dilute binary alloys in the liquid state is briefly reviewed, and its application to certain systems based upon the alkali metals, especially lithium containing small amounts of magnesium, is discussed in quantitative detail. There appears to be a serious discrepancy in the case of Li-Mg, which shows up especially in the temperature variation of the resistivity. It is shown that the Born approximation, upon which the theory is based, may not be entirely valid, but this does not serve to dispose of the discrepancy. The paper includes some remarks about the theory of the Knight shift in liquid alloys.
