VFeCoAs
metal· 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.
