Complex magnetism of B20-MnGe: from spin-spirals, hedgehogs to monopoles
Marcel Bornemann, Sergii Grytsiuk, Paul F. Baumeister +4
B20 compounds are the playground for various non-trivial magnetic textures such as skyrmions, which are topologically protected states. Recent measurements on B20-MnGe indicate no…
Precise Kohn-Sham total-energy calculations at reduced cost
Rudolf Zeller
The standard way to calculate the Kohn-Sham orbitals utilizes an approximation of the potential. The approximation consists in a projection of the potential into a finite subspace…
Lifetime reduction of surface states at Cu, Ag and Au(111) caused by impurity scattering
Swantje Heers, Phivos Mavropoulos, Samir Lounis +2
We present density-functional results on the lifetime of the (111) surface state of the noble metals. We consider scattering on the Fermi surface caused by impurity atoms belonging…
Changing the Magnetic Configurations of Nanoclusters Atom-by-Atom
Samir Lounis, Phivos Mavropoulos, Rudolf Zeller +2
The Korringa-Kohn-Rostoker Green (KKR) function method for non-collinear magnetic structures was applied on Mn and Cr ad-clusters deposited on the Ni(111) surface. By considering v…
The effect of the spin-orbit interaction on the band gap of half-metals
Ph. Mavropoulos, K. Sato, R. Zeller +3
The spin-orbit interaction can cause a nonvanishing density of states (DOS) within the minority-spin band gap of half-metals around the Fermi level. We examine the magnitude of the…
Ballistic Spin Injection from Fe into ZnSe and GaAs with a (001), (111), and (110) orientation
O. Wunnicke, Ph. Mavropoulos, R. Zeller +1
We present first-principles calculations of ballistic spin injection in Fe/GaAs and Fe/ZnSe junctions with orientation (001), (111), and (110). We find that the symmetry mismatch o…
Broken-Bond Rule for the Surface Energies of Noble Metals
I. Galanakis, G. Bihlmayer, V. Bellini +4
Using two different full-potential ab-initio techniques we introduce a simple, universal rule based on the number of broken first-neighbor bonds to determine the surface energies o…
