Density, electrical resistivity and magnetic susceptibility of $\mathrm{Sn}$–$\mathrm{Bi}$ alloys at high temperatures

Temperature dependencies of density (by the gamma-penetrating method), electrical resistivity (by the contact-less method in rotating magnetic field), and magnetic susceptibility (by the Faraday method) of $\mathrm{Sn}$–$\mathrm{Bi}$ alloys with near-eutectic compositions are investigated. The alloy with eutectic composition, $\mathrm{Sn}$ — 58% (mass) $\mathrm{Bi}$, is shown to differ significantly in the electron structure from hypo- and hypereutectic ones. The melt overheating above the given temperature provides the hysteresis of the properties sensitive to electron structure.
