Abstract

PURPOSE:To obtain the magnetic material having a high saturated magnetic flux density and permeability in a high frequency region, excellent in wear resisting property and erosion resisting characteristic by forming the film of metallic oxide with a high permeability on the surface of th powder of the metal magnetic material and shaping it by the sintering process.
