CoPt is a cobalt-platinum intermetallic compound belonging to the hard magnetic alloy family, known for its exceptional magnetic hardness and high ordering temperature. It is primarily employed in permanent magnet applications, magnetic recording media, and high-performance spintronic devices where strong, stable magnetism and thermal stability are critical. CoPt's L1₀ ordered crystal structure makes it particularly valuable in perpendicular magnetic recording and next-generation magnetic storage technologies, where it offers superior coercivity and thermal stability compared to conventional ferromagnetic alloys.
