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…
Anisotropic spin distribution and perpendicular magnetic anisotropy in the layered ferromagnetic semiconductor (Ba,K)(Zn,Mn)As
Shoya Sakamoto, Guoqiang Zhao, Goro Shibata +14
Perpendicular magnetic anisotropy of the new ferromagnetic semiconductor (Ba,K)(Zn,Mn)As is studied by angle-dependent x-ray magnetic circular dichroism measurements. T…
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…
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 (…
Magnetization process of the insulating ferromagnetic semiconductor (Al,Fe)Sb
Shoya Sakamoto, Le Duc Anh, Pham Nam Hai +12
We have studied the magnetization process of the new insulating ferromagnetic semiconductor (Al,Fe)Sb by means of x-ray magnetic circular dichroism. For an optimally doped sample w…
