Graphene has given material scientists countless opportunities, and more importantly, funding:) The morie pattern of multilayer graphene sheets have been presenting various exotic feature, such as strong correlation, superconductivity, and magnetic susceptibility. Recently, multilayer graphene without morie texture, at the rhombohedral pattern, has been shown to presenting many intriguing properties, such as multiferroicity, franctional and integer quantum anomalous Hall effect, etc. Until now, very rare ab initio studies have been conducted to evaluate their magnetic nature. Intuitively, p_z orbital of sp²-carbon could not give finite magnetic moment, and the spin is always paired in the system. We carefully calculate the gate-voltage induced orbital angular momentum in multilayer rhombohedral graphene, which orignates the inter-site cycloid motion. Significantly large magnetc moments (up to 40 Bohr-magneton) can be evaluated at the K and K' valleys, independently. The valley energy can be then modulated under magnetic field. Magnetoresistance pattern and Floquet dressed quantum anomalous Hall (with very large Chern number) effect are also predicted. For details, see our recent work at Phys. Rev.
