Abstract: 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.

Abstract: A nanoparticle is disclosed that has an elongated core extending from a first end to a second end along a longitudinal axis and formed of at least one magnetizable and/or magnetized material. A first cover is formed on a first end of the core, and a second cover is formed on a second end of the core, the first cover and the second cover formed from a magnetocrystalline anisotropic material different than the material of the core. The core is uncovered by the first and second covers along a non-zero longitudinal distance between the first and second covers. In this way, the material of the covers can be reduced in relation to the generated coercive force, which may allow for efficient and reduced-cost permanent magnets.

Abstract: The invention refers to a method for manufacturing a at least 90% relative density of MnBi comprising permanent magnet (7), with a step of synthesizing (ST1a) an anisotropic low temperature phase (LTP) MnBi powder consisting of crystallite particles (1), whereby an aligned and pre-compacted powder is annealed below 628K such that a liquid Bi film (5) is formed around each of the MnBi particles (1).
