where Df is the DOS value at the Fermi level in unit states/eV¡¤cell, and T is the temperature; nm and ne are the thermal excited electrons and valence electron density of the cell, respectively; kB is the Boltzmann constant. ne is calculated by ne = N/Vcell, N is the total number of valence electrons and Vcell is the cell volume. The related parameters and calculated results as shown in Table 6, we can observed that fm increases in the following sequence: MgLa < MgSc < MgY. Thus, the maximal and minimal ¡°metallicity¡± correspond to the MgY and the MgLa, respectively
