Abstract

The magnetic anisotropy energy of iron and nickel were calculated by taking into account the effects of strong electronic correlations, spin-orbit coupling and noncollinearity of intra-atomic magnetization. The dynamical mean-field theory (DMFT) approach was used to study the model Hamiltonian of correlated electron systems in the coupling regimes. The calculations included nonspherical terms of the charge density and potential within the atomic spheres and interstitial region. It was concluded that the change of degenerate fermi surface crossing (DFSC) states was important element that determines the easy axis of nickel.
