Grain Boundary Graphic

Caption

(a) Shows the magnetic MnBi particles/grains separately in the powder. (b) Shows the “bulk” version, where the particles/grains are now touching because of the process of forming the magnet without any added grain boundary materials. (c) Shows the MnBi grains coated with the grain boundary material, illustrating how the grains are no longer touching. The graph illustrates the demagnetization of the magnet in the bulk and powder phases.
