Abstract

The de Haas-van Alphen (dHvA) oscillations of electronic magnetization in a monolayer graphene with structure-induced spin-orbit interaction (SOI) are studied. The results show that the dHvA oscillating centre in this system deviates from the well known (zero) value in a conventional two-dimensional electron gas. The inclusion of SOI will change the well-defined sawtooth pattern of magnetic quantum oscillations and result in a beating pattern. In addition, the SOI effects on Hall conductance and magnetic susceptibility are also discussed.
