· JVASP-132198· Mn28Bi

Mn28Bi is an intermetallic compound in the manganese-bismuth system, representing a research-phase material explored primarily for permanent magnet applications due to its potential ferromagnetic properties. This material belongs to the family of rare-earth-free magnetic alloys being investigated as a sustainable alternative to traditional permanent magnets, with particular interest in high-temperature magnetic applications where conventional rare-earth magnets lose performance. Engineers consider Mn28Bi for next-generation magnetic device designs seeking to reduce dependence on critical rare-earth elements while maintaining functional magnetic characteristics.
