Colossal anomalous Nernst effect in a correlated noncentrosymmetric kagome ferromagnet

T. Asaba et al.

Summary: In UCo0.8Ru0.2Al, a colossal anomalous Nernst effect (ANE) is observed due to strong electronic correlations from uranium's 5f electrons and narrow bands, leading to a large thermoelectric response. Additionally, uranium's strong spin-orbit coupling results in an intrinsic transverse response in this material related to the Berry curvature associated with the relativistic electronic structure.
