Yabin Fan,Xufeng Kou,Pramey Upadhyaya,Qiming Shao,Lei Pan,Murong Lang,Xiaoyu Che,Jianshi Tang,Mohammad Montazeri,Koichi Murata,Li-Te Chang,Mustafa Akyol,Guoqiang Yu,Tianxiao Nie,Kin L. Wong,Jun Liu,Yong Wang,Yaroslav Tserkovnyak,Kang L. Wang +18 more
TL;DR: The effective electric-field control of SOT and the giant spin-torque efficiency in Cr-doped TI may lead to the development of energy-efficient gate-controlled spin-Torque devices compatible with modern field-effect semiconductor technologies.
Journal ArticleDOI
Tailoring exchange couplings in magnetic topological-insulator/antiferromagnet heterostructures
Qing Lin He,Xufeng Kou,Alexander J. Grutter,Gen Yin,Lei Pan,Xiaoyu Che,Yuxiang Liu,Tianxiao Nie,Bin Zhang,Steven Disseler,Brian J. Kirby,William Ratcliff,Qiming Shao,Koichi Murata,Xiaodan Zhu,Guoqiang Yu,Yabin Fan,Mohammad Montazeri,Xiaodong Han,Julie A. Borchers,Kang L. Wang +20 more
TL;DR: Proximity effects are shown to induce an interfacial spin texture modulation and establish an effective long-range exchange coupling mediated by antiferromagnetism, which significantly enhances the magnetic ordering temperature in the superlattice.
