Quantum frequency doubling in the topological insulator Bi2Se3
Pan He, Hiroki Isobe, Dapeng Zhu +3
The nonlinear Hall effect due to Berry curvature dipole (BCD) induces frequency doubling, which was recently observed in time-reversal-invariant materials. Here we report novel ele…
Spin-orbit torque magnetization switching in MoTe2/permalloy heterostructures
Shiheng Liang, Shuyuan Shi, Chuang-Han Hsu +6
The ability to switch magnetic elements by spin-orbit-induced torques has recently attracted much attention for a path towards high-performance, non-volatile memories with low powe…
Nonlinear planar Hall effect
Pan He, Steven S. -L. Zhang, Dapeng Zhu +4
An intriguing property of three-dimensional (3D) topological insulator (TI) is the existence of surface states with spin-momentum locking, which offers a new frontier of exploratio…
Nonlinear magnetotransport shaped by Fermi surface topology and convexity in WTe2
Pan He, Chuang-Han Hsu, Shuyuan Shi +7
The nature of Fermi surface defines the physical properties of conductors and many physical phenomena can be traced to its shape. Although the recent discovery of a current-depende…
Current-enhanced broadband THz emission from spintronic devices
Mengji Chen, Yang Wu, Yang Liu +5
An ultra-broadband THz emitter covering a wide range of frequencies from 0.1 to 10 THz is highly desired for spectroscopy applications. So far, spintronic THz emitters have been pr…
Field-free spin-orbit torque switching from geometrical domain wall pinning
Jong Min Lee, Kaiming Cai, Guang Yang +4
Spin-orbit torques, which utilize spin currents arising from the spin-orbit coupling, offer a novel method to electrically switch the magnetization with perpendicular anisotropy. H…
