Kanagesan, Samikannu and Hashim, Mansor and Jesurani, Sinnappan and Thirunavukarasu, Kalaivani and Ismail, Ismayadi (2014) Microwave sintering of Zn-Nb doped barium hexaferrite synthesized via sol-gel method. Materials Sciences and Applications, 5 (4). pp. 171-176. ISSN 2153-117X; ESSN: 2153-1188


A series of polycrystalline M-type hexagonal ferrites with the formula BaFe12-2xZnx NbxO19 (x = 0.2, 0.4, 0.6, 0.8 mol%) have been synthesized by the sol-gel method. The composition and microstructure govern the magnetic properties of ferrites. The XRD analysis shows the formation of pure magneto plumbite phase without any other impurity phases. The Zn-Nb substitutions in barium hexaferrite have been confirmed through magnetic measurements. The results show that the magnetic properties are closely related to the distributions of Zn-Nb ions on the five crystallographic sites. The saturation magnetization and coercivity increase with increasing Zn-Nb concentration.
