The anomalous Nernst effect (ANE) in topological materials with large Berry curvature shows great potential for transverse thermoelectrics, but antiferromagnets typically show small ANEs. The antiferromagnet YbMnBi2 has an ANE thermopower of 3 μV K−1, similar to ferromagnets, and a larger ANE conductivity.
