  We investigate the spin-dependent thermoelectric effects in magnetic graphene
in both diffusive and ballistic regimes. Employing the Boltzmann and Landauer
formalisms we calculate the spin and charge Seebeck coefficients (thermopower)
in magnetic graphene varying the spin splitting, temperature, and doping of the
junction. It is found that while in normal graphene the temperature gradient
drive a charge current, in the case of magnetic graphene a significant spin
current is also established. In particular we show that in the undoped magnetic
graphene in which different spin carriers belong to conduction and valence
bands, a pure spin current is driven by the temperature gradient. In addition
it is revealed that profound thermoelectric effects can be achieved at
intermediate easily accessible temperatures when the thermal energy is
comparable with Fermi energy $k_BT\lesssim \mu$. By further investigation of
the spin-dependent Seebeck effect and a significantly large figure of merit for
spin thermopower $\mathcal{Z}_{\rm sp}T$, we suggest magnetic graphene as a
promising material for spin-caloritronics studies and applications.
