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 (…
Giant spin-orbit torque in a single ferrimagnetic metal layer
Simon Lenne, Yong-Chang Lau, Ajay Jha +6
Antiferromagnets and compensated ferrimagnets offer opportunities to investigate spin dynamics in the 'terahertz gap' because their resonance modes lie in the 0.3 THz to 3 THz rang…
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…
