The dependence of the magnetic susceptibility on concentration for liquid Pb-Se and Sn-Se alloys exhibited a sharp minimum with a large negative value at the stoichiometric composition, PbSe and SnSe, respectively. Reasonable values of diamagnetic susceptibility on the Se-rich side can be obtained from the relationship between magnetic susceptibility and conductivity. The paramagnetic susceptibility obtained on the metal-rich side can be explained by the decrease in the density of states at the Fermi level and the increase in the enhancement factor with increasing Se composition. The sharp minimum in the concentration dependence of magnetic susceptibility is attributed to the enhancement of diamagnetic susceptibility due to the ion cores and the relatively small value of paramagnetic susceptibility due to the conduction electrons at the stoichiometry.
