Innovative Magnetic Materials Revolutionize Thermoelectric Technology

Researchers from NIMS and UTokyo have developed a new approach to enhance thermoelectric performance using artificially tilted multilayers of magnetic metals and semiconductors. This design leverages the anomalous Nernst effect (ANE) and the off-diagonal Seebeck effect (ODSE) to improve transverse thermoelectric conversion efficiency significantly. The study, published in Nature Communications, suggests that focusing on structural design and specific physical parameters can lead to better materials for practical applications like power generation from waste heat and electronic cooling.
