· JVASP-100642· SmErMn4

SmErMn4 is a rare-earth intermetallic compound combining samarium, erbium, and manganese in a 1:1:4 stoichiometric ratio. This material belongs to the family of rare-earth manganese intermetallics, which are primarily investigated for permanent magnet and magnetocaloric applications due to their magnetic properties and potential for high-temperature performance. SmErMn4 represents an emerging composition in materials research rather than an established commercial alloy, with its utility dependent on the specific magnetic and thermal characteristics that the erbium-samarium combination imparts relative to more conventional rare-earth manganese phases.

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.
