Half-Metallic Ferromagnetism and the spin polarization in CrO
L. Chioncel, H. Allmaier, E. Arrigoni +4
We present electronic structure calculations in combination with local and non-local many-body correlation effects for the half-metallic ferromagnet CrO. Finite-temperature Dyn…
Half-metallic ferromagnetism induced by dynamic electron correlations in VAs
L. Chioncel, Ph. Mavropoulos, M. Ležaić +4
The electronic structure of the VAs compound in the zinc-blende structure is investigated using a combined density-functional and dynamical mean-field theory approach. Contrary to…
Electron Correlations and the Minority-Spin Band Gap in Half-Metallic Heusler Alloys
L. Chioncel, E. Arrigoni, M. I. Katsnelson +1
Electron-electron correlations affect the band gap of half-metallic ferromagnets by introducing non-quasiparticle states just above the Fermi level. In contrast to the spin-orbit c…
