Berry phase effects have significant influences on the electronic properties of condensed matter. In particular, the anomalous Hall conductivity has been recognized as an intrinsic property of the systems with non-zero Berry curvature. Here, we present the anomalous Hall effect observed in the non-magnetic material ZrTe₅, which hosts a large Zeeman splitting with Landé g-factor of 26.49. The quantum oscillation analysis reveals non-linear band dispersion near the top of valence band in bulk band structure, and no Weyl node forms with applied magnetic field. The anomalous Hall conductivity reaches 129 Ω⁻¹cm⁻¹ at 2 K, and shows weak temperature dependence. All these combined with theoretical analysis suggest that the anomalous Hall effect observed in ZrTe₅ originates from the non-vanishing Berry curvature induced by combining large Zeeman splitting and strong spin–orbit coupling. Remarkably, the anomalous Hall resistivity reverses its sign from negative to positive at a hydrostatic pressure P = 1.3 GPa, which confirms that the anomalous Hall effect in ZrTe₅ is highly related to the band structure-dependent Berry curvature. Our results have verified the anomalous Hall mechanism in ZrTe₅ and offer a new platform to study the anomalous Hall effect.

浆果相效应对冷凝物的电子性质有重要影响。特别是，霍尔电导率异常已被认为是具有非零贝里曲率的系统的固有特性。这里，我们提出在非磁性材料ZrTe观察到反常霍耳效应₅，哪些主机与朗德大塞曼分裂克的26.49 -因子。量子振荡分析揭示了在体带结构中价带顶部附近的非线性带分散，并且在施加磁场的情况下不会形成Weyl节点。霍尔电导率异常达到129Ω ^-1 cm ^-1在2 K时，显示出较弱的温度依赖性。所有这些与理论分析相结合，表明在ZrTe _5中观察到的异常霍尔效应起因于大Zeeman分裂和强自旋轨道耦合相结合引起的无消失的Berry曲率。值得注意的是，在静水压力P  = 1.3 GPa时，异常霍尔电阻率将其符号从负反转为正，这证明ZrTe ₅中的异常霍尔效应与能带结构相关的贝里曲率高度相关。我们的研究结果验证了ZrTe ₅的异常霍尔效应机制，并为研究异常霍尔效应提供了一个新的平台。
