· HoFe2

HoFe2 is an intermetallic compound composed of holmium and iron, belonging to the rare-earth transition metal family of materials. This compound is primarily of research and specialized industrial interest, particularly in magnetic applications and high-performance alloy development where the unique magnetic properties of holmium combined with iron's ferromagnetic character offer advantages over conventional magnetic materials. The material is notable in magnetism-driven applications and represents part of the broader class of rare-earth intermetallics being explored for permanent magnets, magnetic refrigeration, and advanced functional alloys where standard ferrous alloys or common rare-earth phases are insufficient.
