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…
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…
Efficient Spintronic THz Emitters Without External Magnetic Field
Amir Khan, Nicolas Sylvester Beermann, Shalini Sharma +4
We investigate the performance of state-of-the-art spintronic THz emitters (W or Ta)/CoFeB/Pt with non-magnetic underlayer deposited using oblique angle deposition. The THz emissio…
OpenFMR: A low-cost open-source broadband ferromagnetic resonance spectrometer
Markus Meinert, Tiago de Oliveira Schneider, Shalini Sharma +1
We describe a broadband ferromagnetic resonance spectrometer for scientific and educational applications with a frequency range up to 30 GHz. It is built with low-cost components a…
