▎ 摘　　要

In this paper the transport properties of normal-ferromagnetic-normal graphene structures are studied by the Landauer Buttiker approach. The properties of spin chiral ferromagnetic layer are investigated when exchange energy exceeds the Fermi energy. To this end, the conductance as well as the shot noise are calculated. The Pauli exclusion principle that acts only on the carriers with the same spin, reduces the shot noise from its Schottky value. The effects of shot noise on the carriers with opposite spins in a ferromagnetic graphene are considered and it is observed that in this case the shot noise is lower than that of non-graphene systems since the quasiparticles with opposite spins are correlated due to chirality. In this way we report a new source of fluctuations in spin chiral materials.
