Radial Rashba spin-orbit fields in commensurate twisted transition-metal dichalcogenide bilayers
Thomas Naimer, Paulo E. Faria Junior, Klaus Zollner +1
In commensurate twisted homobilayers, purely radial Rashba spin-orbit fields can emerge. We employ first-principles calculations to investigate the band structures and the spin-orb…
Resonant magnetic proximity hot spots in Co/hBN/graphene
Klaus Zollner, Lukas Cvitkovich, Riccardo Silvioli +2
Magnetic proximity effects in Co/hBN/graphene heterostructures are systematically analyzed via first-principles calculations, demonstrating a pronounced localized spatial variation…
Machine Learning Prediction of Magnetic Proximity Effect in van der Waals Heterostructures: From Atoms to Moiré
Lukas Cvitkovich, Klaus Zollner, Jaroslav Fabian
We introduce a machine learning framework that efficiently predicts large-scale proximity-induced magnetism in van der Waals heterostructures, overcoming the high computational cos…
Spin injection and detection in all-van der Waals 2D devices
Jan Bärenfänger, Klaus Zollner, Lukas Cvitkovich +7
In this work we report efficient out-of-plane spin injection and detection in an all-van der Waals based heterostructure using only exfoliated 2D materials. We demonstrate spin inj…
Quantum Spin Hall Effect in Magnetic Graphene
Talieh S. Ghiasi, Davit Petrosyan, Josep Ingla-Aynés +9
A promising approach to attain long-distance coherent spin propagation is accessing topological spin-polarized edge states in graphene. Achieving this without external magnetic fie…
