Interplay of growth mode and thermally induced spin accumulation in epitaxial Al/Co${}_2$TiSi/Al and Al/Co${}_2$TiGe/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…
