dc.description.abstract | First-principles method has been applied to calculate the structural, electronic and magnetic properties of the Al1-xMnxN alloys ( with x = 0.0, 0.125, 0.25, 0.375, 0.50, 0.625, 0.75 , 0.875 and 1.00) in the zinc-blende structure (ZB), using FP-LAPW method within the spin-polarized density functional theory. We have studied the band structure and magnetic moment as a function of the lattice parameter of the MnN compound and the ternary alloys Al1-xMnxN. The magnetization increases as the lattice parameter increases and tends to saturate at the value 4µB for MnN and 8 µB for the ternary alloys. We also found that the ternary alloys with x = 0.125 and 0.25 are ferromagnetic in nature and candidate to be half-metallic material; the majority spin states show metallic behavior and the minority spin states show semiconducting behavior. The three concentrations x = 0.375, 0.5 and 0.625 are founded to be semi-metals within the PBE-GGA approach, while they are half metals within the modified Becke-Johnson (mBJ-GGA) approach. The remaining concentrations are found to be semi-metals. It was found that the lattice parameter and the total magnetic moment strongly depend on the Manganese (Mn) concentration. | en_US |
