Theoretical Predict of Half-Metals in Co-Cr-Fe-Al Alloys

To theoretically examine the existence of half-metals in Co-Cr-Fe-Al alloys, band calculations were carried out for these alloys. Seeing energy dispersion curves E(k) of Co2CrAl with the Heusler structure, we find that the Fermi level intersects the E(k) curves in the majority-spin state but is loca... View More
