摘要: The so-called half-metallic magnets have been proposed as good candidates for spintronic applications due to the feature of exhibiting a hundred percent spin polarization at Fermi level. Such materials follow Slater-Pauling rule, which relates magnetic moment with valence electrons in system. In this paper, we study bulk polycrystalline Fe2MnSi Heusler compound replacing Si by Ga determine how addition changes magnetic, structural, and half-metal properties compound. material does not probably minor structural disorder degree system, but linear dependence on transition temperature electron number points behavior
