| Abstract | In this work, we presented a theoretical study on the structural, electronic and magnetic properties of the alloys Mn2RhZ (Z = Si, Ge and Sn) and Mn2YGa (Y = Pt and Ir). The purpose of the work is the investigation of physical parameters such as equilibrium network pitch, compressibility modulus, state density, electronic band structure, magnetic moment and curie temperature. The calculation method used is FP-LAPW which is incorporated into the WIEN2K code in the general framework of density functional theory (DFT), using the generalized gradient density (GGA) approximation. We found that our results are in agreement with the experimental data and that obtained by other methods. All compounds are half-metallic ferromagnetic.
