A Ba₂Co_(2-x)Zn_xFe₁₂O₂₂(x = 0.0 ~ 2.0, Co_(2-x) Y) powder was prepared by a oxidation-coprecipitation method and sintered at 1150 ~ 1250℃ for 4 hours. The microstructures and magnetic properties(saturation magnetization, Curie temperature), complex permeability of sintered body were measured As increasing Zn content from x = 0 to 2.0 in Co_(2-x)Zn_x Y, the real value of complex permeased from 7㎓ to 1㎓. Because of resonance in few ㎓ range, Y-type hexagonal ferrite is more applicalble than spinel ferrite in high frequency range, and more research would be necessary to find the mechanism of the second resonance observed in higher frequency.
