“…The 1/z-corrections lead to a non-trivial structure of the one-particle density of states. In the non-self-consistent approach the integral with the Fermi functions yields, similar to the Kondo problem, the logarithmic singularity (Irkhin and Zarubin, 2000). For very low δ a significant logarithmic singularity exists only in the imaginary part of the Green's function, which corresponds to a finite jump in the density of states (Irkhin and Katsnelson, 1985a).…”

A review of new developments in theoretical and experimental electronic structure investigations of half-metallic ferromagnets (HMF) is presented. Being semiconductors for one spin projection and metals for another ones, these substances are promising magnetic materials for applications in spintronics (i.e., spin-dependent electronics). Classification of HMF by the peculiarities of their electronic structure and chemical bonding is discussed. Effects of electron-magnon interaction in HMF and their manifestations in magnetic, spectral, thermodynamic, and transport properties are considered. Especial attention is paid to appearance of non-quasiparticle states in the energy gap, which provide an instructive example of essentially many-body features in the electronic structure. State-of-art electronic calculations for correlated $d$-systems is discussed, and results for specific HMF (Heusler alloys, zinc-blende structure compounds, CrO$_{2},$ Fe$_{3}$O$_{4}$) are reviewed.Comment: to be published in Reviews of Modern Physics, vol 80, issue
