· JVASP-17476· ErFe2O4

ErFe2O4 is an erbium iron oxide ceramic compound belonging to the spinel or inverse spinel family of mixed-metal oxides. This material is primarily of research and specialized interest rather than widespread industrial production, studied for its magnetic and electronic properties in the context of functional ceramics and magnetic materials. Applications are emerging in magnetic device development, high-temperature magnetic components, and materials research exploring rare-earth oxide systems, where the combination of erbium and iron provides unique electromagnetic behavior that distinguishes it from single-phase oxides or conventional ferrimagnetic ceramics.
