Nanoscale magnet composite for high-performance permanent magnets

摘要

The present invention relates to nanoparticles (n), comprising a of a first end along a longitudinal axis (z) extends a second end extending elongated core (10) which, by means of at least a first, magnetizable and / or a magnetized material is formed; wherein, on the core (10) at the first end of a first cover (20a) and at the second end a second cover (20b) are formed which a second, magneto crystalline anisotropic, material, wherein the core (10) along the longitudinal axis with a distance (d) greater than zero between the first cover (20a) and the second cover (20b), of these is uncovered. In this way, relative to the second material generated coercive field strength can be dispensed with. Correspondingly, cost-saving solutions are offered for permanent magnets.
