Spin-orbit torque generated by amorphous FeSi
Cheng-Hsiang Hsu, Julie Karel, Niklas Roschewsky +5
While tremendous work has gone into spin-orbit torque and spin current generation, charge-to-spin conversion efficiency remains weak in silicon to date, generally stemming from the…

Electric-Field Control of the Interlayer Exchange Coupling for Magnetization Switching
Shehrin Sayed, Cheng-Hsiang Hsu, Niklas Roschewsky +2
We propose an electric-field-controlled mechanism for magnetization switching assisted solely by the interlayer-exchange coupling (IEC) between the fixed and the free magnets, whic…

Spin-Orbit Torque and Nernst Effect in Bi-Sb/Co Heterostructures
Niklas Roschewsky, Emily S. Walker, Praveen Gowtham +4
Harmonic measurements of the longitudinal and transverse voltages in Bi-Sb/Co bilayers are presented. A large second harmonic voltage signal due to the ordinary Nernst effect is ob…
