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…
Two-dimensionality of metallic surface conduction in Co3Sn2S2 thin films
Junya Ikeda, Kohei Fujiwara, Junichi Shiogai +4
Two-dimensional (2D) surface of the topological materials is an attractive channel for the electrical conduction reflecting the linearly-dispersive electronic bands. By applying a…
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…
High-temperature dependence of anomalous Ettingshausen effect in SmCo-type permanent magnets
Asuka Miura, Keisuke Masuda, Takamasa Hirai +6
The anomalous Ettingshausen effect (AEE) in SmCo-type permanent magnets has been investigated in the high-temperature range from room temperature to around 600 K. The anomalous…
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…
