TbFe2Ge2
metal· JVASP-17652· TbFe2Ge2
TbFe2Ge2 is an intermetallic compound combining terbium, iron, and germanium in a 1:2:2 stoichiometry, belonging to the rare-earth transition-metal family of functional materials. This compound is primarily of research and development interest rather than established industrial production, studied for its potential magnetothermoelectric and magnetocaloric properties that could enable advanced refrigeration, energy conversion, and sensing applications. The material's appeal lies in leveraging rare-earth magnetic moments coupled with electronic properties of transition metals and semiconducting germanium, offering potential advantages in specialized applications where conventional alloys fall short.
