论文摘要
磁性与电子带结构拓扑之间的相互作用可能会产生新的外来量子状态。在这里，我们报告了在极性磁性Weyl（WSM）NDALSI中，在温度依赖性的电阻率和特异性中的一种新型的量子振荡。这些新颖的量子现象是由于强烈的Weyl Fermi-4f电子交换与Rashba-Dresselhaus（RD）（RD）和Zeeman效应相结合的强烈的Weyl Fermions-4F电子交换而引起的量子振荡之间的破坏性干扰。我们的发现铺平了一种探索4F电子磁性半法中前所未有的量子现象的方法。
The interplay between magnetism and the topology of electronic band structure may generate new exotic quantum states. Here we report on a new type of quantum oscillations in the temperature dependent electrical resistivity and specific heat at a constant magnetic field in a polar magnetic Weyl semimetal (WSM) NdAlSi. These novel quantum phenomena arise from the destructive interference between quantum oscillations from the spin-split Fermi surfaces due to the strong Weyl fermions-4f electrons exchange interaction combined with Rashba-Dresselhaus (RD) and Zeeman effects. Our findings pave a way to explore unprecedented quantum phenomena in 4f-electron based magnetic semimetals.
