Research paperTheoreticalTopologically Driven Spin-Orbit Torque in Dirac MatterJoaquín Medina Dueñas, José H. García, Stephan RochearXiv·2025·10.48550/arXiv.2408.16359·arXiv:2408.16359AbstractWe unveil novel spin-orbit torque mechanisms driven by topological edge states in magnetic graphene-based devices. Within the energy gap, a damping-like torque plateau emerges within the quantum anomalous Hall phase upon breaking particle-hole symmetry, while for energies at the spin-split Dirac points located within the bands, a large damping-like torque develops as a result of a vanishing Fermi contour. Such torques are tunable by the degree of spin-pseudospin entanglement dictated by proximity-induced spin-orbit coupling terms.Read more
