Low temperature ferromagnetism in (Ga, Mn)N
K. Sato, W. Schweika, P. H. Dederichs +1
The magnetic properties of dilute magnetic semiconductors (DMS) are calculated from first-principles by mapping the ab initio results on a classical Heisenberg model. It is found t…
Half-metallic Zinc-blende Compounds
Ph. Mavropoulos, I. Galanakis, P. H. Dederichs
We report first-principles calculations of zinc-blende half-metals, identifying systems for epitaxial growth with semiconductors, and present calculations for CrAs/GaAs multilayers…
Spin Injection: Interface Resistance in Fe/Semiconductor Junctions Calculated from First Principles
Olaf Wunnicke, Phivos Mavropoulos, Peter H. Dederichs
We calculate the current spin polarisation and the interface resistance of Fe/GaAs and Fe/ZnSe (001) spin injection junctions from first principles, including also the possibility…
A proper ballistic calculation of tunneling conductance for real junctions
P. M. Levy, K. Wang, P. H. Dederichs +4
Employing an ab initio Screened Korringa-Kohn-Rostoker (SKKR) band structure method for a metal-vacuum-metal junction, we find that the tunnel conductance is different when it is c…
Ab initio theory of the interlayer exchange coupling
Josef Kudrnovsky, Vaclav Drchal, Ilja Turek +3
Ab initio formulations of the interlayer exchange coupling (IEC) between two, in general non-collinearly aligned magnetic slabs embedded in a non-magnetic spacer are reviewed where…
