· JVASP-93861· ErMnNi4

ErMnNi4 is an intermetallic compound combining erbium (a rare earth element), manganese, and nickel in a fixed stoichiometric ratio. This material belongs to the family of rare-earth transition metal intermetallics, which are primarily of research and specialized industrial interest rather than commodity applications. ErMnNi4 and related compounds in this family are investigated for potential applications in magnetocaloric refrigeration, permanent magnets, and hydrogen storage systems, where the rare earth and transition metal combination can produce useful magnetic and thermodynamic 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.
