- Press Release
A joint research team from NIMS and the University of Tokyo developed a new composite in which three-dimensional nano-interfaces are distributed throughout the material, by coating the surface of magnetic insulator powders with metal and sintering them. Using this structure, the team succeeded in observing thermoelectric conversion driven by spins in an insulator, a phenomenon previously observed only at nanoscale thin-film interfaces, in a macroscale material. This research result, which provides a new material design paradigm for effectively utilizing thermal energy in insulators, was published in Nature Communications on July 21, 2026.
