Claims

C1strongest claim

We report the observations of the higher odd-order (third-, fifth-, seventh-order) nonlinear Hall effect in magnetic topological insulator Mn(Bi1-xSbx)2Te4 thin flakes. The higher odd-order nonlinear Hall voltage exhibits a twofold angular dependence and exists only below the Néel temperature. It reaches its maximum near the charge neutral point and decays exponentially as the order of the nonlinear Hall effect increases. Theoretical analysis indicates that the higher odd-order nonlinear Hall effect responses may arise from the Berry curvature multipoles.

C2weakest assumption

The measured voltages are genuine higher-order nonlinear Hall responses arising specifically from Berry curvature multipoles rather than from experimental artifacts, heating effects, or other transport mechanisms; this assumption is invoked in the interpretation of angular, temperature, and doping dependence but lacks detailed validation in the abstract.

C3one line summary

Higher odd-order nonlinear Hall effects (third, fifth, and seventh) are observed in Mn(Bi1-xSbx)2Te4 thin flakes and linked to Berry curvature multipoles.
