· JVASP-79586· VFeCoAs

VFeCoAs is a quaternary intermetallic compound combining vanadium, iron, cobalt, and arsenic. This material belongs to the family of Heusler alloys and related magnetic intermetallics, which are primarily of research interest for their potential magnetic and electronic properties. Applications are still largely experimental, with investigation focused on magnetic refrigeration, spintronics, and permanent magnet systems where the unusual magnetic coupling between transition metals offers advantages over conventional alternatives.

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.
