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…
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 (…
Unidirectional planar Hall voltages induced by surface acoustic waves in ferromagnetic thin films
Takuya Kawada, Masashi Kawaguchi, Masamitsu Hayashi
The electromotive forces induced by surface acoustic waves (SAWs) are investigated in ferromagnetic thin films. CoFeB thin films deposited on LiNbO substrates are patterned int…
Dzyaloshinskii-Moriya interaction and spin-orbit torque at the Ir/Co interface
Yuto Ishikuro, Masashi Kawaguchi, Naoaki Kato +2
We studied the spin torque efficiency and the Dzyaloshinskii-Moriya interaction (DMI) of heterostructures that contain interface(s) of Ir and Co. The current-induced shifts of the…
Circular photogalvanic effect in Cu/Bi bilayers
Hana Hirose, Naoto Ito, Masashi Kawaguchi +2
We have studied the circular photogalvanic effect (CPGE) in Cu/Bi bilayers. When a circularly polarized light in the visible range is irradiated to the bilayer from an oblique inci…
