TL;DR: In this article, the anomalous Nernst effect was observed in chiral antiferromagnet Mn3Sn with a very small magnetization, and the transverse Seebeck coefficient at zero magnetic field reached ∼ 0.35?μV?K−1 at room temperature and ∼0.6?μ V?K −1 at 200?K, which is comparable to the maximum value known for a ferromagnetic metal.

TL;DR: Experimental evidence for the realization of magnetic Weyl fermions in the strongly correlated metal Mn3Sn is reported in this paper, which is the only known experimental result for the Weyl Fermion realization.

TL;DR: Experimental evidence is reported for magnetic Weyl fermions in Mn3Sn, a non-collinear antiferromagnet that exhibits a large anomalous Hall effect, even at room temperature, and lays the foundation for a new field of science and technology involving the magnetic Wey excitations of strongly correlated electron systems such as Mn3 Sn.

TL;DR: It is shown that antiferromagnets have richer spin Hall properties than do non-magnetic materials, and a magnetic contribution to the spin Hall effect is observed in the non-collinearantiferromagnet Mn3Sn, which is attributed to momentum-dependent spin splitting produced by non- Collinear magnetic order.

TL;DR: In this paper, the authors identify an antiferromagnetic compound that, due to its exotic electronic structure, shows a strikingly large anomalous Hall effect (AHE) at room temperature.
