The spin Hall effect of Bi-Sb alloys driven by thermally excited Dirac-like electrons
Zhendong Chi, Yong-Chang Lau, Xiandong Xu +3
We have studied the charge to spin conversion in BiSb/CoFeB heterostructures. The spin Hall conductivity (SHC) of the sputter deposited heterostructures exhibits a high…
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…
Symmetry of Berry and spin Berry curvatures in ferromagnetic CoPt
Guanxiong Qu, Kohji Nakamura, Masamitsu Hayashi
The intrinsic spin Hall conductivity and the anomalous Hall conductivity of ferromagnetic L1-CoPt are studied using first principle calculations of the spin Berry and Berry cur…
Magnetization direction dependent spin Hall effect in 3d ferromagnets
Guanxiong Qu, Kohji Nakamura, Masamitsu Hayashi
We have studied the intrinsic spin Hall conductivity of 3d transition metal ferromagnets using first-principles calculations. We find the spin Hall conductivity of bcc Fe and fcc N…
