Electron correlation effects and ferromagnetism in iron
Electron correlation effects in Fe are analysed using a first-principles linear combination of atomic orbitals scheme. In our approach, we first use a local orbital density functional solution to introduce a Hubbard Hamiltonian without fitting parameters. In a second step, we introduce a many-body solution to this Hamiltonian using a dynamical mean-field approximation. Our analysis shows that m...
متن کاملElectron correlation effects in small iron clusters
We present results of first-principles calculations of structural, magnetic, and electronic properties of small Fe clusters. It is shown that, while the lowest-energy isomers of Fe3 and Fe4 obtained in the framework of density functional theory within the generalized gradient approximation (GGA) are characterized by Jahn-Teller-like distortions away from the most regular shapes (which is in agr...
متن کاملCorrelation Effects in Band Ferromagnetism
We analyze the influence of different on-site and inter-site interactions on the Curie temperature of transition metal magnetic elements. The numerical calculations show the well known result that the on-site Coulomb repulsion helps ferromagnetism mainly at half-filling of the band, where the 3d elements are antiferromagnetic (Cr, Mn). The inter-site interactions, which in the new approximation...
متن کاملInvestigation of electron correlation effects in armchair silicene nanoribbons
In this study, the electronic structure of armchair silicene nanoribbons (ASiNRs) is investigated for various widths using first-principle calculations and the framework of the density functional theory. Electronic structure of ASiNRs shows a direct band gap which is decreased with increasing the nanoribbon's width, showing an oscillatory behavior. The effective Coulomb interaction between loca...
متن کاملElectron interactions and ferromagnetism in metals
2014 It is suggested that the effects of electron correlation in metallic ferromagnetics, which must be included in discussions based on the collective electron treatment, could be considered from the point of view of plasma theory, and that some features of the spin wave treatment are thereby introduced.
