Data for the manuscript entitled "Evidence for a field-induced Lifshitz transition in the Weyl semimetal CeAlSi"

This dataset contains the experimental data used in the manuscript "Evidence for a field-induced Lifshitz transition in the Weyl semimetal CeAlSi". It consists mainly of longitudinal resistivity curves as a function of temperature and/or high magnetic fields. These data have been used to study the quantum oscillations present in this material by subtracting smooth backgrounds and performing Fast Fourier Transform on the obtained data. This data set also includes the amplitude of the oscillation as a function of frequency, its evolution with temperature, and Hall resistivity measurements as a function of magnetic field.

本数据集包含学术论文《外尔半金属（Weyl semimetal）CeAlSi中的场致Lifshitz相变证据》所用的实验数据。数据集主体为随温度和/或强磁场变化的纵向电阻率曲线。依托这些数据开展该材料的量子振荡研究时，需先扣除平滑背景，再对所得数据执行快速傅里叶变换（Fast Fourier Transform）。此外，本数据集还涵盖了振荡幅值随频率的变化关系、其随温度的演化特性，以及随磁场变化的霍尔电阻率测量数据。
