Study of Magnetic Performance of Co₂Z Hexaferrite Doped with Nd³⁺

Abstract:

Co₂Z type planar hexaferrite doping of Nd³⁺ 2CoO·3BaO ·xNd₂O₃·(10.8-x) Fe₂O₃ is made with common production process of cermet. The paper studies the influence of Nd₂O₃ doping quantity on microstructure and magnetic performance of Co₂Z type planar hexaferrite. The result indicates that Nd³⁺ doped Co₂Z type ferrite still keeps structure of Z type planar hexagonal, when the doping quantity x=0.050, the magnetic performance in ultrahigh frequency will get improved, the initial permeability can grow to 13, and the cut-off frequency will also relatively reduce to the lowest value 2.131GHz.
