Magnetic topological materials are a realization of topologically nontrivial electronic band structure with magnetic correlation effects; they offer novel opportunities in manipulating charge/spin transport as well as spin texture. In the search for emergent phenomena that are specific in this class of materials, here we report on a type of quantum oscillation of a polar magnetic Weyl semimetal (WSM) NdAlSi in both the temperature dependent electrical resistivity and specific heat at a constant magnetic field. It is revealed that they arise from the destructive interference between field dependent quantum oscillations of the spin-split Fermi surfaces due to the strong Weyl fermion-4f electron exchange interaction combined with Rashba-Dresselhaus and Zeeman effects. Our results demonstrate that the f electrons bearing magnetic WSMs possess even richer responses to external stimuli compared to known d-electron magnetic WSMs and call for further in-depth investigations. © 2023 American Physical Society.
