Abstract
In this paper we present theoretical investigations of electronic and magnetic properties of the ordered cubic ferromagnetic MnSe x S 1 −x MnSe x Te1 −x and MnSe x Po1 −x for x = 025 050 and 075 using the fullpotential 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 MnSe x Te1 −x exhibits a halfmetallic behaviour for all Mn concentrations while MnSeS is halfmetallic only for x = 05 and 075 and MnSePo is halfmetallic only for x = 025 Moreover a total magnetic moment of 5 µB is found for all alloys where the halfmetallic phase is present The total magnetic moment is found to be independent of composition and it is mainly due to the Mn atom
