MnBi NANOPARTICLES, METHOD FOR SYNTHESIZING THE SAME, PROCESS FOR FORMING BULK MnBi MAGNET

摘要

PROBLEM TO BE SOLVED: To provide methods for making a bulk magnet from magnetic nanoparticles which enhance magnetic properties of the bulk magnet.SOLUTION: A method for synthesizing ferromagnetic manganese-bismuth (MnBi) nanoparticles, and the MnBi nanoparticles synthesized by the method, are provided. The method makes use of a novel reagent termed a manganese-based anionic element reagent complex (Mn-LAERC). A process for forming a bulk MnBi magnet from the synthesized MnBi nanoparticles is also provided. The process involves simultaneous application of elevated temperature and pressure to the nanoparticles.SELECTED DRAWING: Figure 4
