Journal ArticleDOI
Blowing magnetic skyrmion bubbles
Wanjun Jiang,Pramey Upadhyaya,Wei Zhang,Guoqiang Yu,M. Benjamin Jungfleisch,Frank Y. Fradin,John E. Pearson,Yaroslav Tserkovnyak,Kang L. Wang,Olle Heinonen,Suzanne G. E. te Velthuis,Axel Hoffmann +11 more
TL;DR: A phase diagram for skyrmion formation is determined and the efficient manipulation of these dynamically created skyrMions, including depinning and motion, are revealed, which could lead to progress in sk Kyrmion-based spintronics.
Journal ArticleDOI
Direct observation of the skyrmion Hall effect
Wanjun Jiang,Wanjun Jiang,Xichao Zhang,Guoqiang Yu,Wei Zhang,Wei Zhang,Xiao Wang,M. Benjamin Jungfleisch,John E. Pearson,Xuemei Cheng,Olle Heinonen,Olle Heinonen,Kang L. Wang,Yan Zhou,Axel Hoffmann,Suzanne G. E. te Velthuis +15 more
TL;DR: In this article, the authors used a current-induced spin Hall spin torque to demonstrate the skyrmion Hall effect, and the resultant SKRIMMion accumulation, by driving SKyrmions from the creep-motion regime (where their dynamics are influenced by pinning defects) into the steady-flow-mode.
Journal ArticleDOI
Switching of perpendicular magnetization by spin-orbit torques in the absence of external magnetic fields
Guoqiang Yu,Pramey Upadhyaya,Yabin Fan,Juan G. Alzate,Wanjun Jiang,Kin L. Wong,So Takei,Scott A. Bender,Li-Te Chang,Ying Jiang,Murong Lang,Jianshi Tang,Yong Wang,Yaroslav Tserkovnyak,Pedram Khalili Amiri,Kang L. Wang +15 more
TL;DR: This work reports the switching of out-of-plane magnetized Ta/Co(20)Fe(60)B(20)/TaO(x) structures by spin-orbit torques driven by in-plane currents, without the need for any external magnetic fields.
Journal ArticleDOI
Magnetization switching through giant spin–orbit torque in a magnetically doped topological insulator heterostructure
Yabin Fan,Pramey Upadhyaya,Xufeng Kou,Murong Lang,So Takei,Zhenxing Wang,Jianshi Tang,Liang He,Li-Te Chang,Mohammad Montazeri,Guoqiang Yu,Wanjun Jiang,Tianxiao Nie,Robert N. Schwartz,Yaroslav Tserkovnyak,Kang L. Wang +15 more
TL;DR: In this article, a magnetically doped topological insulator bilayer is shown to display a range of appealing characteristics for current-induced magnetization switching, including a significantly enhanced efficiency.
Journal ArticleDOI
Skyrmions in magnetic multilayers
TL;DR: In this article, the fundamental topological physics underlying these chiral spin textures, the key factors for materials optimization, and current developments and future challenges are discussed, and a few promising directions that will advance the development of skyrmion based spintronics will be highlighted.
