· O4 Fe2 Er1

O4Fe2Er1 is an iron-erbium oxide compound belonging to the mixed-metal oxide semiconductor family, likely studied for its magnetic and electronic properties resulting from the combination of ferromagnetic iron and rare-earth erbium elements. This is primarily a research-stage material rather than an established commercial compound; compounds in this family are investigated for potential applications in magnetic devices, optoelectronic systems, and high-temperature functional ceramics where the rare-earth element can provide enhanced electronic or magnetic behavior beyond conventional iron oxides.
