· YFe2

YFe2 is an intermetallic compound in the rare-earth iron family, where yttrium combines with iron in a 1:2 stoichiometric ratio. This material belongs to the Laves phase compound group and is primarily investigated for advanced magnetic and high-temperature applications due to its crystalline structure and metal-ceramic hybrid characteristics. Industrial adoption remains limited, with most applications concentrated in research contexts for permanent magnets, magnetocaloric devices, and high-temperature structural components where the rare-earth iron chemistry offers tailored magnetic properties or thermal stability beyond conventional ferrous alloys.
