First principles correspondence of a second type of phonon anomaly along [211] to the Fermi nesting features and associated electron-phonon interactions in Ni${}_2$FeGa

Satyananda Chabungbam, Munima B. Sahariah

First principles calculation supports the occurence of a phonon anomaly along [211] in Ni${}_2$FeGa that was observed experimentally for the first time as structural modulations alon…
