Nonsymmorphic structures are promising to host Dirac and Weyl fermions due to the presence of protected band crossings. The Kondo effect, present in Ce-based compounds, may pin these crossings to the Fermi level, favoring non-trivial topological effects. Here, we report the properties of stoichiometric CeAuBi₂. It crystallizes in the ZrSiS tetragonal P4/nmm nonsymmorphic structure and orders antiferromagnetically below 19 K with a propagation vector (0 0 1/2). At low temperatures, magnetic fields parallel to the c-axis induce several metamagnetic transitions, similar to CeAuSb₂, and a linear positive magnetoresistance is observed, which suggests the presence of band crossings near the Fermi level. The application of external pressure favors the antiferromagnetism. Finally, neutron magnetic diffraction as a function of magnetic field will be discussed.
