Abstract (en)

[origin: EP0764955A1] Composite magnetic material having reduction in the permeability when exposed to a magnetic field of frequencies lower than approximately 100 MHz, consisting of ceramic polycrystalline magnetic plates (5) dispersed in a dielectric binder (6) and orientated so that their faces are parallel to the magnetic field and are in contact with each other. Also claimed are: (i) prodn. of the magnetic material; (ii) a magnetic core consisting of the magnetic material; (iii) inductor comprising the magnetic core; and (iv) a transformer comprising the magnetic core.
