The spin polarization induced by the spin Hall effect (SHE) in thin films typically points out of the plane. This is rooted on the specific symmetries of traditionally studied systems, not in a fundamental constraint. [...]

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.

7 p, 2.2 MB Nonlocal Spin Dynamics in the Crossover from Diffusive to Ballistic Transport / Vila Tusell, Marc (Institut Català de Nanociència i Nanotecnologia) ; Garcia, José H. (Institut Català de Nanociència i Nanotecnologia) ; Cummings, Aron (Institut Català de Nanociència i Nanotecnologia) ; Power, Stephen R. (Institut Català de Nanociència i Nanotecnologia) ; Groth, Christoph W. (Université Grenoble Alpes) ; Waintal, Xavier (Université Grenoble Alpes) ; Roche, Stephan (Institut Català de Nanociència i Nanotecnologia)
Improved fabrication techniques have enabled the possibility of ballistic transport and unprecedented spin manipulation in ultraclean graphene devices. Spin transport in graphene is typically probed in a nonlocal spin valve and is analyzed using spin diffusion theory, but this theory is not necessarily applicable when charge transport becomes ballistic or when the spin diffusion length is exceptionally long.

Since its discovery, graphene has been a promising material for spintronics: its low spin-orbit coupling, negligible hyperfine interaction, and high electron mobility are obvious advantages for transporting spin information over long distances. [...]

7 p, 3.9 MB Tunable circular dichroism and valley polarization in the modified Haldane model / Vila Tusell, Marc (Universitat Autònoma de Barcelona. Departament de Física) ; Hung, Nguyen Tuan (Tohoku University (Japó). Department of Physics) ; Roche, Stephan (Institut Català de Nanociència i Nanotecnologia) ; Saito, Riichiro (Tohoku University (Japó). Department of Physics)
We study the polarization dependence of optical absorption for a modified Haldane model, which exhibits antichiral edge modes in the presence of sample boundaries and has been argued to be realizable in transition metal dichalcogenides or Weyl semimetals. [...]

Basque Foundation for Science)
Graphene is an excellent material for long-distance spin transport but allows little spin manipulation. Transition-metal dichalcogenides imprint their strong spin-orbit coupling into graphene via the proximity effect, and it has been predicted that efficient spin-to-charge conversion due to spin Hall and Rashba-Edelstein effects could be achieved. [...]

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. [...]
