Hall coefficients of liquid metals

Abstract

A very accurate experimental technique is described for the measurement of the Hall coefficients of liquid metals. Measurements having an error factor of 4 less than that of previous work have been made on Hg, In, Tl, and Pb. For Hg and In, the measured Hall coefficient is equal to the free electron value, or the value obtained from an electron concentration equal to the atomic concentration times the valency, 2 for Hg and 3 for In. For Tl and Pb, the measured Hall coefficiert is about 18 and 32% smaller than the respective free electron values, corresponding to a valency of 3 for Tl and 4 for Pb. (H.D.R.)
