· Sm1 Ni5

Sm₁Ni₅ is an intermetallic compound composed of samarium and nickel, belonging to the rare-earth transition-metal semiconductor family. This material is primarily of research interest for its potential in permanent magnet applications and magnetocaloric effects, particularly in cryogenic cooling systems where rare-earth intermetallics are explored as alternatives to conventional refrigerants. The samarium-nickel system is notable for its strong magnetic properties and thermal responsiveness, making it relevant to advanced energy conversion and precision cooling technologies where traditional semiconductors are insufficient.

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.
