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…
