Manganese-based permanent magnets seem to be a recent development in the research literature, could that be the technology employed here? > "Manganese-based permanent magnetic materials have become an area of significant research activity in recent years as a potential alternative to permanent magnets based on Rare Earth (RE) metals. Manganese compounds are capable of achieving a relatively high energy product, BH, when processed to have a strong texture. Research has identified three promising compounds for Mn-based permanent magnets: Mn-Ga, Mn-Bi, and Mn-Al. While calculations show that these compounds cannot achieve the theoretical maximum energy products, (BH)max, of RE magnets, current research suggests than they can fill the property gap between inexpensive, but low-performance, ferrites and expensive high-performance RE magnets."
