Intercorrelated anomalous Hall and spin Hall effect in kagome-lattice CoSnS-based shandite films
Yong-Chang Lau, Junya Ikeda, Kohei Fujiwara +5
Magnetic Weyl semimetals (mWSMs) are characterized by linearly dispersive bands with chiral Weyl node pairs associated with broken time reversal symmetry. One of the hallmarks of m…
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…
Interface enhanced helicity dependent photocurrent in metal/semimetal bilayers
H. Hirose, M. Kawaguchi, Y. -C. Lau +2
One of the hallmarks of light-spin interaction in solids is the appearance of photocurrent that depends on the light helicity. Recent studies have shown that helicity dependent pho…
Giant inverse Faraday effect in Dirac semimetals
Masashi Kawaguchi, Hana Hirose, Zhendong Chi +3
We have studied helicity dependent photocurrent (HDP) in Bi-based Dirac semimetal thin films. HDP increases with film thickness before it saturates, changes its sign when the major…
