Concentration Dependence of the Hall Coefficient in the Magnesium-Cadmium Alloys

抄録

The Hall coefficients of magnesium-cadmium alloys have been measured as a function of composition at both room temperature and 300°C with the magnetic field up to 6.5 KG. For all the compositions, the Hall coefficients are independent of magnetic field. An electronic structure of this system has been discussed with results of the lattice-spacing relations obtained by Hume-Rothery and Raynor. A relation between energy gap and concentration is discussed by comparing their results with the Hall coefficients measured by us. The present experimental results indicate that the energy gaps show a tendency to increase with the addition of cadmium to magnesium.
