· JVASP-123891· TbCo

TbCo is a rare-earth–transition-metal intermetallic compound combining terbium (a lanthanide) with cobalt, typically studied for its magnetic and magnetostrictive properties. This material belongs to the family of rare-earth cobalt systems and is primarily of research interest rather than high-volume production; it is investigated for applications demanding exceptional magnetic performance, magnetostrictive actuation, or high-temperature magnetic stability where the combination of rare-earth magnetism and cobalt's magnetic hardness offers advantages over conventional ferromagnetic alloys.
