· ErFe2

ErFe2 is an intermetallic compound in the rare-earth iron family, combining erbium with iron in a 1:2 stoichiometric ratio. This material exhibits magnetic and structural properties typical of rare-earth intermetallics, making it relevant to high-performance applications requiring controlled magnetic behavior and thermal stability. ErFe2 is primarily of research and specialized industrial interest rather than a commodity material, with applications in magnetic devices, high-temperature structural composites, and materials science investigations into rare-earth metallurgy.
