SmErMn4
metal· 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.
