· JVASP-111011· PrYFe4

PrYFe4 is an intermetallic compound composed of praseodymium, yttrium, and iron, belonging to the rare-earth iron family of functional materials. This material is primarily studied in research contexts for magnetic applications, particularly as a potential permanent magnet material or magnetostrictive device component, where the combination of rare-earth elements enables strong magnetic properties at relatively modest composition costs compared to some competing rare-earth systems. The yttrium addition modifies the crystal structure and magnetic behavior compared to binary Pr-Fe compounds, making it of interest for applications requiring tailored magnetic response or high-temperature magnetic stability.

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.
