Abstract	On an ab initio level, we investigate the recently observed magneto-Seebeckeffect in MgO based tunnel junctions. In particular, we considered ordered CoFe alloys as lead material. Next to the MgO barrier, there are different possible terminations of the CoFe alloy due to the assumed ordered alloy. These results show a strong influence of the termination on the temperature dependence of the magneto-Seebeckeffect. In addition, we use a simple model to account for randomly ordered alloys. We propose, that by a controlled treatment of the CoFe/MgO interface the magneto-Seebeckeffect can be tuned experimentally.
