Thermoelectricity of lithium alloys at very low temperatures

As lithium is apparently the only alkali metal which will take heterovalent impurities into solid solution, we have prepared alloys with Mg, In and Al and examined their absolute thermoelectric power in the temperature range from about 0·1° to 1·2 °k. We find that the change of diffusion thermoelectric power of Li on alloying is in many ways surprising, and we have discussed whether the observed behaviour may reasonably be attributed to the influence of conduction electron scattering or to a change in the electron density of states of lithium.
