Anisotropic Rare Earths-Free Matrix-Bonded High-Performance Permanent Magnet Having A Nanocrystalline Structure, And Method For Production Thereof

摘要

A method for producing a permanent magnet includes coating synthesized nanoparticles with a matrix by a by physical or physical-chemical deposition process, and introducing the matrix-coated nanoparticles into a mold, and exposing the matrix-coated nanoparticles in the mold to an external force field. High fill levels can be achieved in this manner.
