We show that a device made of graphene with Mn adatoms trapped at single vacancies feature spin-dependent Seebeck effect, thus enabling the use of this material for spin caloritronics applications. More than that, it is possible to tune its thermoelectric properties with a gate potential in a way the system presents either a nearly total spin polarized current, flowing in one given direction, or currents for both spins flowing in opposite directions without net charge transport.
