· JVASP-15332· Dy6FeSb2

Dy6FeSb2 is an intermetallic compound combining dysprosium (a rare-earth element), iron, and antimony. This material belongs to the family of rare-earth-transition metal antimonides, which are primarily studied for their thermoelectric and magnetic properties rather than structural applications. While not yet commercially established as a mainstream engineering material, Dy6FeSb2 and related compounds are of research interest for potential thermoelectric energy conversion devices and magnetocaloric applications where rare-earth magnetism combined with electronic properties offers functionality unavailable in conventional alloys.
