Journal ArticleDOI
Room-temperature high spin-orbit torque due to quantum confinement in sputtered BixSe(1-x) films.
Mahendra Dc,Roberto Grassi,Junyang Chen,Mahdi Jamali,Danielle Reifsnyder Hickey,Delin Zhang,Zhengyang Zhao,Hongshi Li,Patrick Quarterman,Yang Lv,Mo Li,Aurelien Manchon,K. Andre Mkhoyan,Tony Low,Jian-Ping Wang +14 more
TL;DR: Sputtered BixSe(1–x) thin films can generate very large current-induced spin–orbit torque, capable to switch both in-plane and out-of-plane magnetized CoFeB-based structures deposited on top, at room temperature.
Journal ArticleDOI
Giant Spin Pumping and Inverse Spin Hall Effect in the Presence of Surface and Bulk Spin−Orbit Coupling of Topological Insulator Bi2Se3
Mahdi Jamali,Joon Sue Lee,Jong Seok Jeong,Farzad Mahfouzi,Yang Lv,Zhengyang Zhao,Branislav K. Nikolić,K. Andre Mkhoyan,Nitin Samarth,Jian-Ping Wang +9 more
TL;DR: Three-dimensional (3D) topological insulators are known for their strong spin-orbit coupling (SOC) and the existence of spin-textured surface states that might be potentially exploited for "topological spintronics."
Journal ArticleDOI
Field-free switching of a perpendicular magnetic tunnel junction through the interplay of spin–orbit and spin-transfer torques
Mengxing Wang,Wenlong Cai,Daoqian Zhu,Zhaohao Wang,Jimmy Kan,Zhengyang Zhao,Kaihua Cao,Zilu Wang,Youguang Zhang,Tianrui Zhang,Chando Park,Jian-Ping Wang,Albert Fert,Albert Fert,Weisheng Zhao +14 more
TL;DR: In this article, the authors show that the threshold current density of spin-orbit torque switching can be reduced by increasing the spin-transfer torque current density, and thus an optimal point for low-power perpendicular magnetic tunnel junction switching can also be found by tuning the two current densities.
Journal ArticleDOI
Room-temperature perpendicular magnetization switching through giant spin-orbit torque from sputtered BixSe(1-x) topological insulator material
Mahendra Dc,Mahdi Jamali,Junyang Chen,Danielle Reifsnyder Hickey,Delin Zhang,Zhengyang Zhao,Hongshi Li,Patrick Quarterman,Yang Lv,Mo Li,K. Andre Mkhoyan,Jian-Ping Wang +11 more
TL;DR: In this article, the spin-orbit torque arising from magnetron-sputtered BixSe(1-x)/CoFeB heterostructures was investigated by using a dc planar Hall method.
Journal ArticleDOI
Spin Hall switching of the magnetization in Ta/TbFeCo structures with bulk perpendicular anisotropy
TL;DR: In this article, the spin-orbit torque in Ta/TbFeCo/MgO patterned structures is investigated in the presence of a perpendicular, longitudinal, or transverse field.
