Native defects in the CoTi ( Si, Ge, Sn) full Heusler alloys: formation and influence on the thermoelectric properties
Voicu Popescu, Peter Kratzer, Sebastian Wimmer +1
We have performed first-principles investigations on the native defects in the full Heusler alloys CoTi ( one of the group IV elements Si, Ge, Sn), determining their form…
Large morphological sensitivity of the magnetothermopower in Co/Cu multilayered systems
Voicu Popescu, Peter Kratzer
We present results of first-principles calculations on the transport properties, both under an electric field or a temperature gradient, in the Co/Cu multilayered systems. The vari…
Interplay of growth mode and thermally induced spin accumulation in epitaxial Al/CoTiSi/Al and Al/CoTiGe/Al contacts
Benjamin Geisler, Peter Kratzer, Voicu Popescu
The feasibility of thermally driven spin injectors built from half-metallic Heusler alloys inserted between aluminum leads was investigated by means of {\em ab initio} calculations…
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…
