YbFe2
metal· JVASP-19801· YbFe2
YbFe2 is an intermetallic compound in the rare-earth iron family, combining ytterbium with iron in a 1:2 stoichiometric ratio. This material is primarily of research and specialized interest rather than mainstream industrial production, explored for its magnetic and magnetocaloric properties that emerge from the rare-earth–transition metal combination. Applications focus on advanced thermal management and magnetic devices where the interplay between ytterbium's electronic structure and iron's magnetic contribution offers potential advantages over simpler ferromagnetic alloys, though practical engineering use remains limited compared to conventional magnetic steels or permanent magnets.
