NANOSCALE MAGNET COMPOSITE FOR HIGH-PERFORMANCE PERMANENT MAGNETS

摘要

The invention relates to nanoparticles (N), comprising an elongated core (10), which extends from a first end to a second end along a longitudinal axis (z) and which is formed by means of at least one first, magnetizable and/or magnetized material; wherein a first cover (20a) is formed on the core (10) at the first end and a second cover (20b) is formed on the core at the second end, the first cover and the second cover having a second, magnetocrystalline anisotropic material, wherein the core (10) is not covered by the first cover or the second cover along the longitudinal axis having a distance (d) greater than zero between the first cover (20a) and the second cover (20b). In this way, second material can be spared in relation to the generated coercive force. Accordingly, cost-saving solutions for permanent magnets are possible.
