The electronic structure, magnetic and elastic properties were predicted for Full Heusler Alloy-Ir2FeGe using local spin density approximation as implemented in Wien2k. The exchange-correlation potential is treated with the local density approximations LDA. The optimized lattice constant was 2.13% lower than the predicted value. This material is metallic and ferromagnetic. The energy level close to Fermi is mainly occupied by Ir-d and Fe-d-electrons. We accorded more attention to the elastic constants, where we have derived bulk and shear modules with employing Voigt–Reuss–Hill approach. The ferromagnetic performance of Ir₂FeGe is confirmed by the total magnetic moment of 3.50 μB per formula unit, where its main contribution is originated from Fe atoms.
