Investigation of crystal structure and dielectric response in BaTiO3-BaFe12O19 multiferroic composites
The composites of BaFe12O19 and BaTiO3 having composition xBaTiO3 - (1-x)BaFe12O19 (x=0.10 and 0.20) were prepared by commercial solid state reaction method. The Rietveld refinement revealed the hexagonal phase with space group P63/mmc for BaFe12O19 and tetragonal phase with space group P4mm for BaTiO3. No appreciable phase changes take place in samples. The dielectric response of dielectric constant (e′) and dielectric loss (tanδ) in the low frequency region was analyzed in the light of Maxwell Wagner model. Further impedance studies help to study the microstructure of the material and also show the grain and grain boundary contribution in the prepared samples.
