Observation of Hubbard Bands in -Manganese
S. Biermann, A. Dallmeyer, C. Carbone +5
We present angle-resolved photoemission spectra of the -phase of manganese as well as a theoretical analysis using a recently developed approach that combines density functional…
Effect of local Coulomb interactions on the electronic structure and exchange interactions in Mn12 magnetic molecules
D. W. Boukhvalov, A. I. Lichtenstein, V. V. Dobrovitski +4
We have studied the effect of local Coulomb interactions on the electronic structure of the molecular magnet Mn12-acetate within the LDA+U approach. The account of the on-site repu…
Magnetism of correlated systems: beyond LDA
A. I. Lichtenstein, M. I. Katsnelson
A novel approach to electronic correlations in magnetic crystals which takes into account a dynamical many-body effects is present. In order to to find a frequency dependence of th…
Finite-temperature magnetism of transition metals: an LDA+DMFT approach
A. I. Lichtenstein, M. I. Katsnelson, G. Kotliar
We present an ab initio quantum theory of the finite temperature magnetism of iron and nickel. A recently developed technique which combines dynamical mean-field theory with realis…
