Abstract (en)
[origin: WO2011054746A1] The invention relates to a method for producing a magnet (1), wherein the magnet (1) is formed from at least one magnetic material (3) and one binding agent (4) and is subsequently hardened. According to the invention, a metal oxide (8) that is chemically bonded to the magnetic material (3) is produced from the binding agent (4) during hardening. The invention further relates to a magnet (1) and an electric machine.
