Electrical resistivities of liquid alkaline earth metals

Abstract

Measurements of the resistivities of liquid Mg, Ca, Sr and Ba are described. The values obtained at the melting point are, respectively, 26.1, 33.0, 84.8 and 30.6 mu Omega cm. Resistivities calculated with the aid of three model pseudopotentials are in the range 7 to 21 mu Omega cm. The discrepancies between the observed and calculated resistivities are discussed in terms of recent contributions to pseudopotential theory.
