Abstract : The magnetic susceptibility at room temperature, and the temperature dependence of susceptibility of the mercury-indium liquid alloys system has been measured by the Curie method for In concentrations of up to about 60 atomic percent. Measurements were made at closely-spaced intervals of In concentration in the range 0 to 5 weight percent in which region an unexplained thermopower anomaly had been observed by previous workers. No corresponding susceptibility anomaly was observed. However, an examination of the deviation from linearity of chi (In) revealed special regions corresponding to Hg: In atomic ratios of 4:1 (12.5 weight percent In) and 1:1 (36 weight percent In) respectively. The susceptibility of Pure Hg at 20C, obtained by extrapolating the alloy data to zero In concentration was -0.1667 mir emu/gm. The temperature dependence of susceptibility of Pure Hg was not linear, but the temperature coefficient taken between 20C and 120C was 0.96 x 0.01 mir emu/gm-deg. (Author)
