Sign reversal of Berry curvature triple driven by magnetic phase transition in a ferromagnetic polar metal
Xuyang Sha, Xuejin Zhang, Hao Liu +10
While the time-reversal-even (T-even) nonlinear Hall effect has been extensively discussed in nonmagnetic materials, the impact of magnetic phase transition on it remains largely o…

Large nonlinear Hall effect and Berry curvature in KTaO3 based two-dimensional electron gas
Jinfeng Zhai, Mattia Trama, Hao Liu +6
The two-dimensional electron gas (2DEG) at oxide interfaces exhibits various exotic properties stemming from interfacial inversion symmetry breaking. In this work, we report the em…
