TbPrFe4
metal· JVASP-109684· TbPrFe4
TbPrFe4 is an intermetallic compound combining terbium, praseodymium, and iron, representing a rare-earth transition metal alloy. This material belongs to the family of rare-earth iron-based intermetallics, which are typically investigated for magnetic and high-temperature applications where strong magnetic coupling and thermal stability are required. The specific combination of heavy rare earths (Tb, Pr) with iron positions this alloy for potential use in permanent magnets, magnetostrictive devices, and high-temperature magnetic applications where conventional ferromagnets lose performance.
