Using ab initio methods, we study transport and thermoelectric phenomena of magnetic organic chains containing nitroxide groups. We demonstrate that such systems appear to be half‐metallic ferromagnets with considerable energy gap between spin‐up and spin‐down channels. This means that an appropriate device could act as a very effective spin filter and its polarization may be changed with use of the gate voltage. Also, we predict very good thermoelectric performance of the structure, as the conventional and spin Seebeck coefficients are remarkably enhanced. These results suggest that magnetic organic chains would have a great potential for applications in spintronic devices.
