Optimal spin-charge interconversion in graphene through spin-pseudospin entanglement control
Joaquín Medina Dueñas, Santiago Giménez de Castro, Jose H. Garcia +1
The electrical generation of spin signals is of central interest for spintronics, where graphene stands as a relevant platform as its spin-orbit coupling (SOC) is tuned by proximit…
Topologically Driven Spin-Orbit Torque in Dirac Matter
Joaquín Medina Dueñas, José H. García, Stephan Roche
We 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 with…
Emerging Spin-Orbit Torques in Low Dimensional Dirac Materials
Joaquín Medina Dueñas, José H. García, Stephan Roche
We report a theoretical description of novel spin-orbit torque components emerging in two-dimensional Dirac materials with broken inversion symmetry. In contrast to usual metallic…
