Room-temperature third-order nonlinear Hall effect in Weyl semimetal TalrTe4
文献摘要：
The second-order nonlinear Hall effect observed in the time-reversal symmetric system has not only shown abundant physical content,but also exhibited potential application prospects.Recently,a third-order nonlinear Hall effect has been observed in MoTe2 and WTe2.However,few-layer MoTe2 and WTe2 are usually unstable in air and the observed third-order nonlinear Hall effect can be measured only at low temperature,which hinders further investigation as well as potential application.Thus,exploring new air-stable material systems with a sizable third-order nonlinear Hall effect at room temperature is an urgent task.Here,in type-Ⅱ Weyl semimetal TaIrTe4,we observed a pronounced third-order nonlinear Hall effect,which can exist at room temperature and remain stable for months.The third-order nonlinear Hall effect is connected to the Berry-connection polarizability tensor instead of the Berry curvature.The possible mechanism of the observation of the third-order nonlinear Hall effect in TaIrTe4 at room temperature has been discussed.Our findings will open an avenue towards exploring room-temperature nonlinear devices in new quantum materials.
