· JVASP-35064· SmMnSi

SmMnSi is an intermetallic compound composed of samarium, manganese, and silicon, belonging to the rare-earth intermetallic family. This material is primarily investigated in research contexts for magnetocaloric and magnetostrictive applications, where the combination of rare-earth and transition metals enables strong magnetic coupling and thermal-magnetic interactions. SmMnSi and related compounds are evaluated for solid-state refrigeration, magnetic actuators, and high-performance magnetic sensor systems where conventional materials fall short.

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.
