Iron-rich compounds with the tetragonal ThMn12-type structure have the potential to meet current demands for rare-earth-lean permanent magnets with high energy density and operating temperatures of 150–200 °C. However, while it is normal for magne

Mn–Bi alloys modified with Mg and other elements were recently developed into promising rare-earth-free permanent magnets through successive melt spinning, warm compaction, and short magnetic field annealing. This letter reports on the crystal stru

Melt-spun Mn50Bi50-xSbx alloys with x ≤ 5 were prepared at different solidification rates and characterized both in the as-spun state and after annealing. In the as-spun alloys, the Sb substitution leads to the formation of a metastable phase, simi

A bulk magnet based on Sm-Fe-V with the ThMn12 crystal structure has been fabricated for the first time by hot-compaction of mechanically milled powders with a density of 92% of the theoretical density. The isotropic magnet exhibits a maximum coerciv

In recent years, infiltration of hot-deformed Nd-Fe-B magnets with liquid Nd- and Pr-rich alloys has been intensively studied as a cost-effective way of increasing the magnet coercivity $H_{{\text{c}}}$ and, ultimately, its maximum operating temperat
