Non-quasiparticle states in Co${}_2$MnSi evidenced through magnetic tunnel junction spectroscopy measurements

L. Chioncel, Y. Sakuraba, E. Arrigoni +6

We investigate the effects of electronic correlations in the full-Heusler Co${}_2$MnSi, by combining a theoretical analysis of the spin-resolved density of states with tunneling-cond…
