Charge-to-spin conversion in epitaxial and polycrystalline Bi and Bi/Ag layers
Federica Nasr, Emir Karadža, Santos F. Alvarado +9
Bi is predicted to be an efficient generator of spin-orbit torques (SOTs), with charge-to-spin conversion efficiency comparable to those of prototypical heavy metals, such as Ta, W…
Direct Observation of Antimagnons with Inverted Dispersion
Hanchen Wang, Junfeng Hu, Wenjie Song +14
We report direct spectroscopic evidence of antimagnons, i.e., negative-energy spin waves identified by their signature inverted dispersion and left-handed precession with Brillouin…
Nonlinear longitudinal and transverse magnetoresistances due to current-induced magnon creation-annihilation processes
Paul Noël, Richard Schlitz, Emir Karadža +4
Charge-spin conversion phenomena such as the spin Hall effect allow for the excitation of magnons in a magnetic layer by passing an electric current in an adjacent nonmagnetic cond…
Mitigation of Gilbert Damping in the CoFe/CuOx Orbital Torque System
Shilei Ding, Hanchen Wang, William Legrand +2
Charge-spin interconversion processes underpin the generation of spin-orbit torques in magnetic/nonmagnetic bilayers. However, efficient sources of spin currents such as 5d metals…
Spin-orbit torques and magnetization switching in Gd/Fe multilayers generated by current injection in NiCu alloys
Federica Nasr, Federico Binda, Charles-Henri Lambert +3
Light transition metals have recently emerged as a sustainable material class for efficient spin-charge interconversion. We report measurements of current-induced spin-orbit torque…
Spin-orbit torques and spin Hall magnetoresistance generated by twin-free and amorphous Bi0.9Sb0.1 topological insulator films
Federico Binda, Stefano Fedel, Santos Francisco Alvarado +2
Topological insulators have attracted great interest as generators of spin-orbit torques (SOTs) in spintronic devices. Bi\textsubscript{1-x}Sb\textsubscript{x} is a prominent topol…
