Abstract

See full text

The claimed invention provides a wet chemical method to prepare manganese bismuth nanoparticles having a particle diameter of 5 to 200 nm. When annealed at 550 to 600K in a field of 0 to 3 T the nanoparticles exhibit a coercivity of approximately 1 T and are suitable for utility as a permanent magnet material. A permanent magnet containing the annealed MnBi nanoparticles is also provided.
