Helicity dependent photovoltaic effect in Bi2Se3 under normal incident light
Jean Besbas, Karan Banerjee, Jaesung Son +7
Topological insulators (TIs) form a new class of materials with insulating bulk and surface conduction ensured by topologically protected surface states (TPSS). We investigate the…
Spin orbit torques and Dzyaloshinskii-Moriya interaction in dual-interfaced Co-Ni multilayers
Jiawei Yu, Xuepeng Qiu, Yang Wu +5
We study the spin orbit torque (SOT) and Dzyaloshinskii-Moriya interaction (DMI) in the dual-interfaced Co-Ni perpendicular multilayers. Through the combination of top and bottom l…
High performance THz emitters based on ferromagnetic/nonmagnetic heterostructures
Yang Wu, Mehrdad Elyasi, Xuepeng Qiu +4
We report a THz emitter with excellent performances based on nonmagnetic (NM) and ferromagnetic (FM) heterostructures. The spin currents are first excited by the femtosecond laser…
Enhanced spin-orbit torque via modulation of spin current absorption
Xuepeng Qiu, William Legrand, Pan He +5
The magnitude of spin-orbit torque (SOT), exerted to a ferromagnet (FM) from an adjacent heavy metal (HM), strongly depends on the amount of spin currents absorbed in the FM. We ex…
