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

TL;DR: In this article, the spin transfer torque switching in nano-scale perpendicular magnetic tunnel junctions with a magnetoresistance ratio up to 249% and a resistance area product as low as 7.0
Journal ArticleDOI
Skyrmions in Magnetic Tunnel Junctions
Xueying Zhang,Wenlong Cai,Xichao Zhang,Zilu Wang,Zhi Li,Yu Zhang,Kaihua Cao,Na Lei,Wang Kang,Yue Zhang,Haiming Yu,Yan Zhou,Weisheng Zhao +12 more
TL;DR: It is demonstrated that skyrmions can be nucleated in the free layer of a magnetic tunnel junction (MTJ) with Dzyaloshinskii-Moriya interactions (DMIs) by a spin-polarized current with the assistance of stray fields from the pinned layer.
Journal ArticleDOI
Exchange bias switching in an antiferromagnet/ferromagnet bilayer driven by spin–orbit torque
Shouzhong Peng,Daoqian Zhu,Weixiang Li,Hao Wu,Alexander J. Grutter,Dustin A. Gilbert,Dustin A. Gilbert,Jiaqi Lu,Danrong Xiong,Wenlong Cai,Padraic Shafer,Kang L. Wang,Weisheng Zhao +12 more
TL;DR: In this article, the current-induced switching of the exchange bias field in a perpendicularly magnetized IrMn/CoFeB bilayer structure using a spin-orbit torque generated in the antiferromagnetic IRMn layer was reported.
