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.
