· Fe4 Er2

Fe₄Er₂ is an intermetallic compound combining iron and erbium (a rare earth element) that exhibits semiconductor behavior. This material belongs to the rare earth-iron intermetallic family, which has attracted research interest for magnetic and electronic applications due to erbium's strong magnetic moment and iron's abundance. Fe₄Er₂ remains largely experimental; its practical development depends on demonstrating cost-effective synthesis routes and thermal stability, but the material family shows promise in applications where controlled magnetic properties and semiconductor characteristics are simultaneously valuable.

Export Control

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
