PURPOSE: To provide the oxide magnetic material suitable for the constitution of a magnetic core for an antenna coil and an inductance element for electronic equipment used in the high-frequency band of 200-500MHz such as pagers (pocket bells) and the like. CONSTITUTION: This is the oxide magnetic material for the magnetic core of a coil used in a high-frequency band. The compositions of the base material at the sintering are Fe2O3: 15-30mol%, CuO: 6-12mol% and Nip: 58-79mol%. With the total quantity of the base material as the reference, the adding components of PbO: 1.0-5.0wt.%, SiO2: 0.5-3.7wt.% and Cod: 0.7-2.5wt.% are contained. |
