PROBLEM TO BE SOLVED: To provide a magnetic material for high frequency that can be baked at a temperature lower than the melting point of silver, has high permeability in a high frequency region, and is less in magnetic loss even at >=300 MHz by replacing part of the composition of a cobalt-barium-strontium ferrite which is one kind of ferroxplana with another element. SOLUTION: This magnetic material for high frequency has a composition expressed by the chemical formula: (2+3x)(Co0.55 Cu0.45 ) O.3(Ba0.75 Sr0.15 Bix Can0.1-x )O1+x/2 .(9.8-3x/2)Fe2 O3 (wherein x is a molar ratio of 0<=x<=0.1). |
