Magnetic interactions in Cu-containing heterospin polymer
A. V. Postnikov, A. V. Galakhov, S. Bluegel
The electronic structure of Cu hexafluoroacetylacetonate, crystallized with a stable nitronyl nitroxide radical [Ovcharenko et al., Russ. Chem. Bull. 53, 2406 (2004)], is calculate…
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…
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…
Ab initio Simulations of Fe-based Ferric Wheels
A. V. Postnikov, Jens Kortus, Stefan Bluegel
Based on first-principles density-functional theory calculations we investigate the electronic structure of hexanuclear "ferric wheels" M Fe_6[N(CH_2 CH_2 O)_3]_6 Cl (M = Li, Na) i…
X-ray photoelectron 3s spectra of transition metal oxides
V. R. Galakhov, S. Uhlenbrock, S. Bartkowski +6
We present metal 3s x-ray photoelectron spectra of different transition metal oxides. The values of the 3s exchange splitting for the 3d metal oxides are given as a function of the…
