TbFe2Si2
metal· JVASP-15568· TbFe2Si2
TbFe2Si2 is an intermetallic compound combining terbium, iron, and silicon in a stoichiometric ratio, belonging to the rare-earth iron silicide family of materials. This compound is primarily investigated in research contexts for magnetocaloric and magnetostructural applications, where its magnetic properties at cryogenic temperatures make it relevant to cooling technologies and magnetic refrigeration systems. The combination of a rare-earth element with transition metals and silicon creates strong magnetic interactions, distinguishing it from conventional structural alloys and positioning it as a candidate material for advanced energy conversion and low-temperature device engineering.
