Reduction of g-factor due to Rashba effect in graphene

Graphene is a highly promising material in the field of spin electronics. Recent experiments on electron resonance have observed reduction g-factor graphene. In our previous paper [J. Phys. Soc. Jpn. 88, 094707 (2019)], we demonstrated that one sources for this diamagnetic property However, by itself does not fully account magnitude experiments. paper, focus Rashba effect, which caused work function existing near surface The effect tilts magnetic moment to in-plane direction graphene sheet, potentially reducing g-factor. We evaluate using simple model system incorporating and Zeeman effects. then demonstrate resultant close agreement with prior experiments, indicating able remaining
