In this paper, we conduct a theoretical investigation on the thermal spin transport properties of three devices based on magnetic C28monomolecular, using the non-equilibrium Green’s function combined with density functional theory. By applying a temperature field, we observe that these devices lead to a spin-dependent Seebeck effect; some devices also embody spin-dependent Seebeck diode effectand negative differential resistance effect. The physical mechanism was explained using the Fermi-Dirac distribution and spin transmission spectrum. These interesting effects suggest that these three devices can be used as new spin nanodevices.
