Journal ArticleDOI
Half-metallic ferromagnets: From band structure to many-body effects
TL;DR: A review of new developments in theoretical and experimental electronic-structure investigations of half-metallic ferromagnets (HMFs) is presented in this article, where the effects of electron-magnon interaction in HMFs and their manifestations in magnetic, spectral, thermodynamic, and transport properties are considered.
Journal ArticleDOI
Correlated metals and the LDA + U method
TL;DR: In this article, the LDA Stoner approach was extended to weakly correlated metals and a constrained density functional theory was proposed to derive a version of LDA+U$ that is consistent with the Hohenberg-Kohn theorem.
Journal ArticleDOI
Multiple-scattering formalism for correlated systems: A KKR-DMFT approach
J. Minár,Liviu Chioncel,Alexander Perlov,Hubert Ebert,Mikhail I. Katsnelson,Alexander I. Lichtenstein +5 more
TL;DR: In this article, a charge and self-energy self-consistent computational scheme for correlated systems based on the Korringa-Kohn-Rostoker (KKR) multiple scattering theory with the many-body effects described by the means of dynamical mean field theory (DMFT) is presented.
Journal ArticleDOI
Nonquasiparticle states in the half-metallic ferromagnet NiMnSb
Liviu Chioncel,Mikhail I. Katsnelson,Mikhail I. Katsnelson,de Robert Groot,Alexander I. Lichtenstein +4 more
TL;DR: In this paper, the spectral weight of NiMnSb was evaluated and the possible experimental investigation (Bremsstrahlung isohromat spectroscopy, nuclear magnetic resonance, scanning tunneling microscopy and Andreev reflection) was discussed.
Journal ArticleDOI
Nonquasiparticle states in Co2MnSi evidenced through magnetic tunnel junction spectroscopy measurements.
Liviu Chioncel,Liviu Chioncel,Yuya Sakuraba,Enrico Arrigoni,Mikhail I. Katsnelson,Mikihiko Oogane,Yasuo Ando,Terunobu Miyazaki,Emil Burzo,Alexander I. Lichtenstein +9 more
TL;DR: In this article, the effects of electronic correlations in the full-Heusler Co2MnSi were investigated by combining a theoretical analysis of the spin-resolved density of states with tunneling-conductance spectroscopy measurements.
