PROBLEM TO BE SOLVED: To provide a sintered ferrite compact, capable of obtaining a wideband absorbing property. SOLUTION: This is a soft-magnetism hexagonal sintered ferrite compact and has a chemical composition of BaO: 17.5-21.5mol%, Fe2 O3 : 64-67.5mol%, and CoO: 13.5-18.5mol%. The production ratio of the phase of Y-type construction, represented by Ba2 Co2 Fe12 O22 to the phase of z-type construction represented by Ba3 Co2 Fe12 O41 , is within a range of 3:7 to 7:3. |
