Abstract
The magnetic susceptibility at room temperature, and the temperature dependence of susceptibility of the mercury-indium liquid alloy system, have been measured by the Curie method for In concentrations of up to about 60 at. %. Measurements were made at closely spaced intervals of In concentration in the range 0 to 6 at. %, in which region an unexplained thermopower anomaly had been observed by previous workers. An examination of the deviation from linearity of χ([In]) revealed special regions corresponding to Hg : In atomic ratios of 4 : 1 (12.5 wt. at. % In) and 1 : 1 (36 wt. at. % In) respectively, suggestive of loose atomic associations in the liquid. Alternatively the susceptibility results could be interpreted as lending some support to Mott's recent theory of the electronic structure of amalgams.
