Electric-field control of spin-orbit torque in a magnetically doped topological insulator
Yabin Fan, Xufeng Kou, Pramey Upadhyaya +16
Electric-field manipulation of magnetic order has proved of both fundamental and technological importance in spintronic devices. So far, electric-field control of ferromagnetism, m…
Magnetism-induced massive Dirac spectra and topological defects in the surface state of Cr-doped BiSe-bilayer topological insulators
C. -C. Chen, M. L. Teague, L. He +6
Proximity-induced magnetic effects on the surface Dirac spectra of topological insulators are investigated by scanning tunneling spectroscopic (STS) studies of bilayer structures c…
Enhancing Magnetic Ordering in Cr-doped Bi2Se3 using High-TC Ferrimagnetic Insulator
Wenqing Liu, Liang He, Yongbing Xu +11
We report a study of enhancing the magnetic ordering in a model magnetically doped topological insulator (TI), Bi2-xCrxSe3, via the proximity effect using a high-TC ferrimagnetic i…
Scale-Invariant Dissipationless Chiral Transport in Magnetic Topological Insulators beyond the Two-Dimensional Limit
Xufeng Kou, Shih-Ting Guo, Yabin Fan +12
We investigate the quantum anomalous Hall Effect (QAHE) and related chiral transport in the millimeter-size (Cr0.12Bi0.26Sb0.62)2Te3 films. With high sample quality and robust magn…
Switching of perpendicular magnetization by spin-orbit torques in the absence of external magnetic fields
Guoqiang Yu, Pramey Upadhyaya, Yabin Fan +10
Magnetization switching by current-induced spin-orbit torques (SOTs) is of great interest due to its potential applications for ultralow-power memory and logic devices. In order to…
