Description:

(abstract)

Topological magnets such as magnetic Weyl and nodal-line semimetals possess topologically non-trivial band structures in magnetically ordered states. In this class of materials, the Berry curvature in momentum space can be significantly enhanced, resulting in thermoelectric responses that exceed empirical scaling laws based on magnetization. Such large transverse thermoelectric effects enable flexible thin-filmbased lateral device structures, leading to novel energy-harvesting technologies and sensors beneficial for Internet of Things (IoT) sensors and wearable devices. In this review, we outline recent progress in the study of the large transverse thermoelectric effects in topological magnets.
