Thermoelectric devices enable heat-electricity conversion, but achieving a large Nernst effect typically requires strong magnetic fields. Here, the authors demonstrate that YbMnBi2, with its unique band topology and magnetic order, exhibits a remarkably high anomalous Nernst thermopower among magnetic materials, offering a promising route for efficient transverse thermoelectric applications.
