The nonlinear Hall effect (NLHE), the phenomenon in which a transverse voltage can be produced without a magnetic field, provides a potential alternative for rectification or frequency doubling1,2. However, the low-temperature detection of the NLHE limits its applications3,4. Here, we report the room-temperature NLHE in a type-II Weyl semimetal TaIrTe4, which hosts a robust NLHE due to broken inversion symmetry and large band overlapping at the Fermi level. We also observe a temperature-induced…

Nonlinear anomalous Hall effect in few-layer WTe2
TLDR
A nonlinear anomalous Hall effect, allowed for certain point group symmetries, is observed in metallic WTe2, and can be understood as an AHE induced by the bias current, which generates an out-of-plane magnetization.
