· JVASP-55386· TbFe3B4O12

TbFe3B4O12 is a rare-earth iron borate ceramic compound containing terbium, iron, and boron oxide phases. This material is primarily investigated in research contexts for magnetic and optical applications, leveraging the strong magnetic properties of terbium combined with iron's ferrimagnetic behavior in a borate host structure. It represents an emerging material family with potential in high-performance magnetic devices, though industrial adoption remains limited compared to established rare-earth magnets and ceramics.
