Abstract

We have investigated the magnetic and microwave absorbing properties of barium hexaferrite BaFe 12-2x Co x Zn x O 19 (x = 0.0; 0.2; 0.4; 0.6) nanocrystalline prepared using solid state reaction method. The powder of these ferrites were resulted by high energy ball mill for 1 h and mixed with epoxy resin to be converted into a microwave absorbing composite. The results show barium hexaferrite structures for Ba(Fe,Co,Zn) 12 O 19 have been formed. The coercive force (Hc) decreases rapidly with the substitution of Co and Zn in the structure of Ba(Fe,Co,Zn) 12 O 19 . It's indicate that the Co-Zn in the structure of Ba(Fe,Co,Zn) 12 O 19 contributes to magnetic and microwave absorption properties. The minimum reflection loss value of -29.98 dB was observed at 10.8 GHz with a matching thickness of 1 mm for BaFe 12-2x Co x Zn x O 19 (x = 0.6) nanocrystalline. As results, the magnetic absorbing properties improve significantly by Co-Zn incorporation.
