· EuS

Europium sulfide (EuS) is a rare-earth compound semiconductor with a rock-salt crystal structure, combining the lanthanide element europium with sulfur. This material is primarily of research and specialized device interest rather than high-volume industrial production, valued for its unique magnetic and optical properties that arise from europium's partially filled 4f electron shell. EuS finds applications in magnetooptic devices, spin-dependent electronics, and as a model system for studying ferromagnetic semiconductors and magnetic phenomena at the nanoscale.

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.
