▎ 摘  要

This paper elucidates the combined effect of intrinsic spin-orbit interaction (ISOI) and perpendicular electric field (E-z) on edge states in finite graphene-like nanoribbons. It is shown that the ISOI generates magnetic anisotropy which makes the in-plane edge magnetization configuration more energetically stable than the commonly studied out-of-plane one. The anisotropy less severely suppresses the former configuration than the latter. As concerns the E-z effect, the following evolution of electric transport properties is predicted: magnetic insulator, non-magnetic narrow-band semiconductor, and finally non-magnetic band insulator.
