Researchers have discovered a giant thermoelectric effect in an antiferromagnet. The study shows, surprisingly, that antiferromagnets can have the same value of the anomalous Nernst effect as conventional ferromagnets, but without any stray magnetic fields that would otherwise affect surrounding devices. The newly discovered recipe for generating large Nernst voltages opens a new research direction for the development of highly efficient thermoelectric devices.
