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…
