· JVASP-15426· TmFe2Ge2

TmFe2Ge2 is an intermetallic compound combining thulium (a rare-earth element), iron, and germanium in a stoichiometric ratio. This material is primarily of research interest rather than widespread industrial use, studied for its magnetic and electronic properties within the rare-earth intermetallic family. Engineers and materials researchers investigate compounds like this for potential applications in high-performance magnets, thermoelectric devices, and quantum materials where the coupling between rare-earth magnetism and transition-metal electronic structure offers unique functional behavior.
