1. IntroductionIn recent years, electromagnetic (EM) and magnetic methods have been essential in geophysical exploration, widely applied in subsurface detection for identifying targets with varying electrical and magnetic properties [1,2,3,4]. However, traditional inversion techniques face significant limitations, including susceptibility to local minima and dependence on initial values, which can lead to inaccurate results.

AbstractThe 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.
