The noncentrosymmetric ferromagnetic Weyl semimetal CeAlSi with simultaneous space-inversion and time-reversal symmetry breaking provides a unique platform for exploring novel topological states. Here, by employing multiple experimental techniques, we demonstrate that ferromagnetism and pressure can serve as efficient parameters to tune the positions of Weyl nodes in CeAlSi. At ambient pressure, a magnetism-facilitated anomalous Hall/Nernst effect (AHE/ANE) is uncovered. Angle-resolved photoemission spectroscopy (ARPES) measurements demonstrated that the Weyl nodes with opposite chirality are moving away from each other upon entering the ferromagnetic phase. Under pressure, by tracing the pressure evolution of AHE and band structure, we demonstrate that pressure could also serve as a pivotal knob to tune the positions of Weyl nodes. Moreover, multiple pressure-induced phase transitions are also revealed. These findings indicate that CeAlSi provides a unique and tunable platform for exploring exotic topological physics and electron correlations, as well as catering to potential applications, such as spintronics.

具有同时空间反演和时间反演对称性破缺的非中心对称铁磁Weyl半金属CeAlSi为探索新颖的拓扑态提供了独特的平台。在这里，通过采用多种实验技术，我们证明铁磁性和压力可以作为调整 CeAlSi 中 Weyl 节点位置的有效参数。在环境压力下，发现了磁促进的反常霍尔/能斯特效应（AHE/ANE）。角分辨光电子能谱（ARPES）测量表明，具有相反手性的韦尔节点在进入铁磁相时正在相互远离。在压力下，通过追踪 AHE 和能带结构的压力演变，我们证明压力也可以作为调节 Weyl 节点位置的关键旋钮。此外，还揭示了多种压力诱导的相变。这些发现表明，CeAlSi 提供了一个独特且可调的平台，用于探索奇异的拓扑物理和电子相关性，并满足自旋电子学等潜在应用的需求。
