Terahertz Phase Inversion via Field-Free Spin-Orbit Torque Switching in an Antenna-Integrated Spintronic Heterostructure
Amir Khan, Tiago de Oliveira Schneider, Suraj Joshi +4
We demonstrate microsecond-timescale electrical control of the terahertz (THz) emission phase in broadband field-free spintronic THz emitters, enabling megahertz-rate phase inversi…

Uniaxial Magnetic Anisotropy and Type-X/Y Current-Induced Magnetization Switching in Oblique-Angle-Deposited Ta/CoFeB/Pt and W/CoFeB/Pt Heterostructures
Amir Khan, Shalini Sharma, Tiago de Oliveira Schneider +1
Planar current-induced magnetization switching (CIMS) driven by spin-orbit torque (SOT) requires an in-plane uniaxial magnetic anisotropy (UMA), which can be induced by oblique-ang…

Spin Hall effect in the high-resistivity high-entropy alloy AlCrMoW
Jyoti Yadav, Felix Janus, Tiago de Oliveira Schneider +3
We study thin films of the high-entropy alloy system Al(CrMoW), grown on Ta seed layers by magnetron co-sputtering. Between and , a resistivity larger…
