Half-metallic ferromagnets for magnetic tunnel junctions
Phivos Mavropoulos, Marjana Lezaic, Stefan Bluegel
Using theoretical arguments, we show that, in order to exploit half-metallic ferromagnets in tunneling magnetoresistance (TMR) junctions, it is crucial to eliminate interface state…
Fe clusters on Ni and Cu: size and shape dependence of the spin moment
Ph. Mavropoulos, S. Lounis, R. Zeller +1
We present ab-initio calculations of the electronic structure of small Fe clusters (1-9 atoms) on Ni(001), Ni(111), Cu(001) and Cu(111) surfaces. Emphasis is given on the spin mome…
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…
