The magnetic susceptibility of liquid Na–Sn alloys has been measured as a function of temperature and concentration. The curve of susceptibility isotherm exhibits a distinct minimum around the composition of Na4Sn3 near the liquidus temperature. At the same composition, the remarkable temperature dependence has also been observed, and the minimum point in the susceptibility isotherm shifts from Na4Sn3 to NaSn at higher temperatures. This large temperature variation has been explained in terms of the partial dissociation of the compound-forming liquid alloy.
