Heusler compounds have been very interesting material because of its inherent properties, which make them valuable for spin-dependent materials. In this paper, structural optimization along with electronic properties of Fe2MnAl and Fe2MnSi full Heusler compounds have been calculated by using the FP-LAPW method. Both materials found to be half-metallic by showing metallic character within a spin-up and semiconducting character in a spin-down state. Energy and correlation potential have been anticipated by using GGA approximation which gave an idea about the stable ground state. Both materials were stable in the Fm-3m (225) space group.
