Abstract
In this paper, we present theoretical investigations of electronic and magnetic properties of the ordered cubic ferromagnetic MnSexS1 −x, MnSexTe1 −x, and MnSexPo1 −x for x = 0.25, 0.50, and 0.75 using the full-potential linearized augmented plane wave method. Regarding structural properties, we found that the lattice parameters of MnSeS, MnSeTe, and MnSePo alloys follow Vegard’s law. Results show that MnSexTe1 −x exhibits a half-metallic behaviour for all Mn concentrations, while MnSeS is half-metallic only for x = 0.5 and 0.75, and MnSePo is half-metallic only for x = 0.25. Moreover, a total magnetic moment of 5 µB is found for all alloys where the half-metallic phase is present. The total magnetic moment is found to be independent of composition and it is mainly due to the Mn atom.
