· TbCo2B2

TbCo2B2 is an intermetallic compound combining terbium, cobalt, and boron, belonging to the rare-earth transition-metal boride family. This material is primarily of research interest for advanced functional applications, particularly where the magnetic properties of terbium combined with cobalt's ferromagnetic behavior and boron's hardening effects are leveraged. Engineers and materials scientists investigate such compounds for potential use in high-performance magnetic devices, permanent magnets, and hard coatings, though industrial-scale production and deployment remain limited compared to more established rare-earth alloys.
