Abstract

Measurements of the Hall coefficient and electrical conductivity are reported for solutions of lithium in liquid ammonia. The concentration range is from 1.2 to 14 mol % metal (MPM) and the temperature range is from near 200 to 240°K, except in the miscibility gap. Hall coefficients equal to the values expected from the metal-valence-electron density are found above 9 MPM. Below 9 MPM the measured Hall coefficient Rm increases to about twice the free-electron value R0. The latter result does not agree with that previously reported by Kyser and Thompson. Rm is temperature independent at all concentrations. Data for the electrical conductivity σ show thermal activation of the mobility below 8 MPM. Changes in the concentration dependence of both Rm and σ are observed near 3, 5, and 8 MPM. The solutions behave as liquid metals above 9 MPM. As the concentration is decreased from 9 to 3 MPM, departure from metallic behavior occurs and various criteria for metallic conduction are no longer satisfied. We believe deep traps are present below 9 MPM. At concentrations near 3 MPH the influence of free electrons is no longer seen.
