  • Magnetic film and a method for the production thereof
    Patent number: 6464894
    Abstract: The invention relates to hard magnetic films made of a polymer matrix and hard magnetic powder particles distributed therein. The films have a thickness of preferably 100 to 500 &mgr;m and are flexible. They can be produced by using a casting method and are suited, for example, as hard magnetic components in miniature motors, polarized relays or sensors.
