· TmFe2Si2

TmFe₂Si₂ is an intermetallic compound combining thulium (a rare-earth element), iron, and silicon in a fixed stoichiometric ratio. This material belongs to the rare-earth iron silicide family and is primarily studied in research contexts for its potential magnetic and thermal properties, rather than as an established commercial alloy. The rare-earth–transition-metal silicide class is investigated for applications requiring controlled magnetic behavior, high-temperature stability, or specialized electronic properties where conventional steels or nickel-based superalloys are insufficient.
