First principles investigations of Fe2CrSi Heusler alloys by substitution of Co at Fe site
2018
Electronic structure and magnetic properties of Fe2-xCoxCrSi Heusler alloys have been investigated by varying Co concentration from x = 0 to 2. On increasing Co concentration, lattice constant and magnetic moment of Fe2-xCoxCrSi alloys increase. These alloys show true half metallic Ferromagnetic behavior with 100% spin polarization. Band gap of the alloys also increase from 0.54 eV to 0.85 eV on increasing Co concentration making these alloys promising materials for spintronics based device applications.
