Effect of multi-layering and crystal orientation on spin-orbit torque efficiency in Ni/Pt layer stacking
A. Sud, Y. -C. Lau, J. Brierley +2
We study spin-orbit torques (SOTs) in Ni/Pt bi-layers and multi-layers by ferromagnetic resonance (FMR) and harmonic-Hall measurements. The effect of multi-layering and crystal ori…
Highly fcc-textured Pt-Al alloy films grown on MgO(001) showing enhanced spin Hall efficiency
Yong-Chang Lau, Takeshi Seki, Koki Takanashi
We report on a systematic comparative study of the spin Hall efficiency between highly face-centered cubic (fcc)-textured Pt-Al alloy films grown on MgO(001) and poorly-crystallize…
Spin Hall effect in a spin-1 chiral semimetal
Ke Tang, Yong-Chang Lau, Kenji Nawa +7
Spin-1 chiral semimetal is a new state of quantum matter hosting unconventional chiral fermions that extend beyond the common Dirac and Weyl fermions. B20-type CoSi is a prototypal…
Magnetization switching induced by spin-orbit torque from Co2MnGa magnetic Weyl semimetal thin films
Ke Tang, Zhenchao Wen, Yong-Chang Lau +3
This study reports the magnetization switching induced by spin-orbit torque (SOT) from the spin current generated in Co2MnGa magnetic Weyl semimetal (WSM) thin films. We deposited…
Interlayer exchange coupling through Ir-doped Cu spin Hall material
Hiroto Masuda, Takeshi Seki, Yong-Chang Lau +2
Metallic superlattices where the magnetization vectors in the adjacent ferromagnetic layers are antiferromagnetically coupled by the interlayer exchange coupling through nonmagneti…
Giant perpendicular magnetic anisotropy in Ir/Co/Pt multilayers
Yong-Chang Lau, Zhendong Chi, Tomohiro Taniguchi +8
We have studied the magnetic properties of multilayers composed of ferromagnetic metal Co and heavy metals with strong spin orbit coupling (Pt and Ir). Multilayers with symmetric (…
