PURPOSE:To provide a soft magnetic material, which does not require to perform a sintering and moreover, is superior in high-frequency characteristics. CONSTITUTION:A mixed powder of a chemical compositional ratio of NiO:CuO: ZnO:Fe2O3=15:6:31:48 is fired to obtain spinel type ferrite powder of a particle diameter of longer than 10nm and shorter than 7mum. For example, a resin is mixed in this spinel type ferrite powder to mold the mixture into a prescribed molded material and the molded material is formed into a molded article. This molded article is superior in high-frequency characteristics and if the particle diameter of the spinel type ferrite powder is longer than 10nm and shorter than 7mum, the molded article, which is superior in high-frequency characteristics, can be obtained by merely molding, in short, without going through a sintering process. |
