· JVASP-15579· ErFe2Ge2

ErFe2Ge2 is an intermetallic compound combining erbium (a rare earth element), iron, and germanium in a Heusler-type crystal structure. This is a research-phase material studied primarily for its magnetic and electronic properties rather than a commercially established engineering material. The compound is of interest in condensed matter physics and materials research for potential applications in magnetocaloric devices, magnetic refrigeration systems, and spintronics, where the interplay between rare earth magnetism and transition metal ferromagnetism can be engineered for specific functional properties.

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.
