Engineering 2D material heterostructures by combining the best of different materials in one ultimate unit can offer a plethora of opportunities in condensed matter physics. Here, in the van der Waals heterostructures of the ferromagnetic insulator CrGeTe and graphene, our observations indicate an out-of-plane proximity-induced ferromagnetic exchange interaction in graphene.

Dirac materials such as graphene and topological insulators (TIs) are known to have unique electronic and spintronic properties. We combine graphene with TIs in van der Waals heterostructures to demonstrate the emergence of a strong proximity-induced spin-orbit coupling in graphene. [...]

15 p, 1.0 MB 1D ferromagnetic edge contacts to 2D graphene/h-BN heterostructures / Karpiak, Bogdan (Chalmers University of Technology (Göteborg, Suècia)) ; Dankert, André (Chalmers University of Technology (Göteborg, Suècia)) ; Cummings, Aron (Institut Català de Nanociència i Nanotecnologia) ; Power, Stephen R. (Institut Català de Nanociència i Nanotecnologia) ; Roche, Stephan (Institut Català de Nanociència i Nanotecnologia) ; Dash, Saroj P. (Chalmers University of Technology (Göteborg, Suècia))
We report the fabrication of one-dimensional (1D) ferromagnetic edge contacts to two-dimensional (2D) graphene/h-BN heterostructures. While aiming to study spin injection/detection with 1D edge contacts, a spurious magnetoresistance signal was observed, which is found to originate from the local Hall effect in graphene due to fringe fields from ferromagnetic edge contacts and in the presence of charge current spreading in the nonlocal measurement configuration.
