Standard model of the rare-earths, analyzed from the Hubbard I approximation
I. L. M. Locht, Y. O. Kvashnin, D. C. M. Rodrigues +10
In this work we examine critically the electronic structure of the rare-earth elements by use of the so-called Hubbard I approximation. From the theoretical side all measured featu…
Microscopic origin of Heisenberg and non-Heisenberg exchange interactions in ferromagnetic bcc Fe
Y. O. Kvashnin, R. Cardias, A. Szilva +6
By means of first principles calculations we investigate the nature of exchange coupling in ferromagnetic bcc Fe on a microscopic level. Analyzing the basic electronic structure re…
Exchange parameters of strongly correlated materials: extraction from spin-polarised density functional theory plus dynamical mean field theory
Y. O. Kvashnin, O. Grånäs, I. Di Marco +3
In this paper we present an accurate numerical scheme for extracting inter-atomic exchange parameters () of strongly correlated systems, based on first-principles full-pote…
