PROBLEM TO BE SOLVED: To overcome problem wherein means for attaining a high permeability, e.g. magnetic field orientation or hot press, is required for a FeOx planar mag netic material, and to produce a magnetic material for high frequency exhibiting high permeability in high frequency region without requiring any special system or process, e.g. magnetic field orientation or hot press. SOLUTION: The magnetic material for high frequency exhibiting high permeability in high frequency region is represented by a general composition formula of Ba3 Co2 Mx Fe24-x O41 , where M is Gd or Dy. When M is Gd, 0.0075<=x<=0.7 and when M is Dy, 0.01<=x<=0.8. |
