· JVASP-5095· TbFeSi

TbFeSi is an intermetallic compound combining terbium, iron, and silicon, belonging to the rare-earth metal alloy family. This material is primarily of research interest for magnetocaloric and magnetostrictive applications, where controlled magnetic properties enable advanced functionality in cooling systems and precision actuators. The incorporation of terbium—a lanthanide rare earth element—makes this compound notable for its potential in next-generation magnetic technologies that demand superior magnetic response compared to conventional ferromagnetic alloys.
