· JVASP-23808· ErMn12

ErMn₁₂ is an intermetallic compound combining erbium (a rare-earth element) with manganese, belonging to the family of rare-earth transition-metal compounds. This material is primarily of research interest for its magnetic properties, particularly in applications requiring high magnetic moments or unusual magnetic behavior at elevated temperatures. ErMn₁₂ and related rare-earth manganese phases are explored for permanent magnets, magnetic refrigeration systems, and magnetostrictive actuators where conventional ferromagnets or ferrimagnets fall short in performance or operational range.

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.
