First principle studies of electronic structure and magnetic properties binary alloy Fe2Ge are presented. We have observed the increase total moment per unit cell with lattice dilation. The underlying cause for this increased moments is explained in terms structure. found that dilation has facilitated band filling especially majority spin resulting increasing moment. Later, we reasoned out interaction between Fe non-magnetic germanium atoms responsible Fe2Ge. From current studies, insight gained allowed us to explain experimentally magneto-resistance thin films.
