Spintronic properties of 2D systems and their potential when in contact with magnetic atoms are discussed for the examples of topological insulator (TI) and graphene systems [1-5].
The interface between ferromagnetic and non-magnetic Bi2Se3 phases is presented as a material platform to investigate the influence of time-reversal symmetry breaking and band bending effect of spin degrees of freedom on 3D TI properties. Their impact on 2D magnetotransport is shortly discussed.
