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…
Acoustic spin Hall effect in strong spin-orbit metals
Takuya Kawada, Masashi Kawaguchi, Takumi Funato +2
We report on the observation of the acoustic spin Hall effect that facilitates lattice motion induced spin current via spin orbit interaction (SOI). Under excitation of surface aco…
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…
Highly efficient spin orbit torque in Pt/Co/Ir multilayers with antiferromagnetic interlayer exchange coupling
Yuto Ishikuro, Masashi Kawaguchi, Tomohiro Taniguchi +1
We have studied the spin orbit torque (SOT) in Pt/Co/Ir multilayers with 3 repeats of the unit structure. As the system exhibits oscillatory interlayer exchange coupling (IEC) with…
