Stabilization of itinerant (band) magnetism in FeAl by Ga substitution for Al

Stabilization of itinerant (band) magnetism in FeAl by Ga substitution for Al

Band structure calculations of FeGa1−xAlx have been performed, to further investigate the stability of ferromagnetism in FeAl. The Stoner parameter increases by about 20% at the FeGa end. This is also confirmed by our spin-polarized calculations. We conclude that Ga substitution for Al is likely to...

Zusammenfassung:Band structure calculations of FeGa1−xAlx have been performed, to further investigate the stability of ferromagnetism in FeAl. The Stoner parameter increases by about 20% at the FeGa end. This is also confirmed by our spin-polarized calculations. We conclude that Ga substitution for Al is likely to stabilize the elusive (or illusive) ferromagnetic state in FeAl.
