Exchange parameters in Fe-based molecular magnets
A. V. Postnikov, G. Bihlmayer, S. Bluegel
The calculation of interatomic magnetic exchange interactions entering the Heisenberg model from the standpoint of the density functional theory (DFT) is outlined for two Fe-based…
Lattice dynamics of mixed semiconductors (Be,Zn)Se from first-principles calculations
A. V. Postnikov, Olivier Pages, Joseph Hugel
Vibration properties of Zn(1-x)Be(x)Se, a mixed II-VI semiconductor haracterized by a high contrast in elastic properties of its pure constituents, ZnSe and BeSe, are simulated by…
Isolated modes and percolation in lattice dynamics of (Be,Zn)Se
A. V. Postnikov, O. Pages, T. Tite +2
A mixed II-VI semiconductor Zn[1-x]Be[x]Se possesses non-trivial vibration properties, because its two constituent compounds, ZnSe and BeSe, show very different degree of covalency…
Exchange interactions and magnetic anisotropy in the "Ni_4" magnetic molecule
A. V. Postnikov, M. Brueger, J. Schnack
Magnetic properties of a tetrahedral "Ni_4" molecule are discussed in terms of the Heisenberg model, with magnetic anisotropy terms included, and on the basis of first-principle ca…
