The Thermoelectric Power of Magnesium-Cadmium Alloys

概要

論文の詳細を見る
The thermoelectric power of magnesium-cadmium alloys was measured relative to pure copper at temperatures between room temperature and 300℃. The measurements were made in the entire ranges of the composition and the data were analyzed by a band-model approximation to obtain some information about the band structure of the alloys in the magnesium-cadmium system. The thermoelectric power at 300℃ as a function of composition shows a smooth trend as well as that of an earlier investigation of the Hall measurements, although the result of the thermoelectric power at room temperature shows that there are three maxima and two minima, while the result of the Hall coefficient gives two maxima and one minimum. In the alloys of the composition corresponding to the ordered phase, anomalies in the thermoelectric power are observed at the transition point. The results of the thermoelectric power indicate that there is no evidence of any extinction or initiation of a band by the alloying. The situation of the Fermi level in A-overlap is discussed.
