ANISOTROPIC RARE EARTHS-FREE PLASTIC-BONDED HIGH-PERFORMANCE PERMANENT MAGNET HAVING NANOCRISTALLINE STRUCTURE, AND METHOD FOR PRODUCTION THEREOF

摘要

The invention relates to a method for producing a permanent magnet (PM), comprising the steps of mixing and coating (V) synthesized nanoparticles (1) with a plastics matrix (3), said step being carried out in the liquid phase, and orienting and shaping the dried matrix-coated nanoparticles (5) that are introduced into a mold and exposed to an external magnetic field (M). High degrees of filling are obtained.
