By employing Landauer–Buttiker formalism,we first investigate the thermally-driven spin transport through a transverse-biased magnetic zigzag-edge graphene nanoribbon.It is shown that a critical source temperature is needed to generate a spin-polarized current due to the presence of a forbidden transport gap.
