High-$T_c$ $d^0$ ferromagnetism in a doped Mott insulator: the case of hydrogenated epitaxial graphene on SiC(0001)

Pengcheng Chen, Yuanchang Li, Wenhui Duan

We show that the $d^0$ ferromagnetism with high Curie temperature ($T_c$) can be achieved in the electron doped hydrogenated epitaxial graphene on some certain SiC substrates thr…
