Field-free-switching state diagram of perpendicular magnetization subjected to conventional and unconventional spin-orbit torques
D. J. P. de Sousa, P. M. Haney, J. P. Wang +1
The lack of certain crystalline symmetries in strong spin-orbit-coupled non-magnetic materials allows for the existence of uncoventional spin Hall responses, with electrically gene…
Current-induced torques in magnetic Weyl semimetal tunnel junctions
D. J. P. de Sousa, Fei Xue, J. P. Wang +2
We study the current-induced torques in asymmetric magnetic tunnel junctions containing a conventional ferromagnet and a magnetic Weyl semimetal contact. The Weyl semimetal hosts c…
Giant Anomalous Hall Effect due to Double-Degenerate Quasi Flat Bands
Wei Jiang, Duarte J. P. de Sousa, Jian-Ping Wang +1
We propose a novel approach to achieve giant AHE in materials with flat bands (FBs). FBs are accompanied by small electronic bandwidths, which consequently increases the momentum s…
Dirac spectrum in gated multilayer black phosphorus nanoribbons
J. D. S. Forte, D. J. P. de Sousa, J. Milton Pereira
We investigate the effects of a perpendicular electric field applied to multilayer phosphorene nanoribbons with zigzag and armchair edges. Within the context of the tight-binding m…
