| description | The invention relates to a method for producing a permanent magnet (20), comprising the steps: (a) providing a powder of a magnetic material (12), (b) coating the powder particles with a coating of a diamagnetic or paramagnetic coating material, (c) compressing the coated particles to form a pressed part, (d) heat treatment to sinter the coating material (17) at a temperature less than a temperature suitable for sintering the magnetic material (12), while the coating material transfers to a matrix (21) of a diamagnetic or paramagnetic material (22), which embeds the particles of the magnetic material (12), and (e) magnetising the magnetisable material (12) in an external magnetic field, wherein the steps (c), (d) and (e) are carried out in any order successively or at the same time in any desired combination. The nanostructured permanent magnet (20) that can be produced by means of said method comprises cores (15) of a permanently magnetic material (12) having a mean particle diameter of no more than [mu]m and a matrix (21) of a diamagnetic or paramagnetic material (22) in which the cores (15) are embedded. |
