Spin-orbitronics at a topological insulator-semiconductor interface
T. Guillet, C. Zucchetti, A. Marchionni +9
Topological insulators (TIs) hold great promises for new spin-related phenomena and applications thanks to the spin texture of their surface states. However, a versatile platform a…
Unveiling multiferroic proximity effect in graphene
Fatima Ibrahim, Ali Hallal, Daniel Solis Lerma +3
We demonstrate that electronic and magnetic properties of graphene can be tuned via proximity of multiferroic substrate. Our first-principles calculations performed both with and w…
Self-induced inverse spin Hall effect in ferromagnets: demonstration through non-monotonous temperature-dependence in permalloy
O. Gladii, L. Frangou, A. Hallal +12
We investigated the self-induced inverse spin Hall effect in ferromagnets. Temperature (T), thickness (t) and angular-dependent measurements of transverse voltage in spin pumping e…
Graphene-based spinmechatronic valve
Ali Hallal
Interlayer twist between van der Waals graphene crystals led to the discovery of superconducting and insulating states near the magic angle. In this work, we exploit this mechanica…
Proximity magnetoresistance in graphene induced by magnetic insulators
D. A. Solis, A. Hallal, X. Waintal +1
We demonstrate the existence of Giant proximity magnetoresistance (PMR) effect in a graphene spin valve where spin polarization is induced by a nearby magnetic insulator. PMR calcu…
Very large Dzyaloshinskii-Moriya interaction in two-dimensional Janus manganese dichalcogenides and its application to realize skyrmion states
Jinghua Liang, Weiwei Wang, Haifeng Du +5
The Dzyaloshinskii-Moriya interaction (DMI), which only exists in noncentrosymmetric systems, is responsible for the formation of exotic chiral magnetic states. The absence of DMI…
