· JVASP-37461· SmMn3

SmMn3 is an intermetallic compound composed of samarium and manganese, belonging to the rare-earth manganese family of materials. This compound is primarily of research interest for its magnetic properties, particularly in applications requiring controlled magnetization or magnetocaloric effects, and has been studied as a candidate material for magnetic refrigeration and magnetostrictive device applications. While not yet widely deployed in mainstream engineering, SmMn3 exemplifies the class of rare-earth intermetallics that offer tunable magnetic characteristics as alternatives to conventional ferromagnets and permanent magnets in specialized cooling and sensing systems.

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.
