The concerted effort of relativistic spin-orbit interaction, electronic band topology and magnetic order in antiferromagnetic Weyl semimetals (WSM-AFMs) manifests itself in novel properties, crucial for development of antiferromagnetic spintronics. We quantified magnetotransport properties of polycrystalline and epitaxial WSM-AFM/heavy-metal structures which revealed signatures of chiral anomaly in condensed matter systems. We utilized anomalous Nernst effect for different crystallographic orientations (C and M-plane) of the epitaxial structure. Our observations show an electronic route towards characterization of topological nature of electronic bands in Weyl semimetals.
