Abstract
Strontium zinc zirconium hexaferrites/polyaniline (Sr(ZnZr) x Fe 12−2 x O 19–PANI, x=0, 0.5, 1.0) composites were synthesized by oxidative chemical polymerization of aniline in the presence of ammonium peroxydisulfate (APS). The structure and morphology of the product was characterized by FTIR, TGA and SEM. The particle size of the core material was found to be about 250–500 nm. After coating with polyaniline, the particle size of Sr(ZnZr) 0.5Fe 11O 19–PANI composites grew upto 0.5–1.0 μm. XRD of the ferrites indicated that the structure of the core materials is hexagonal, with lattice constants around 5.886–5.885 Å. It was found that the saturation magnetization ( M S) and coercivity ( H C) for Sr(ZnZr) x Fe 12−2 x O 19–PANI composites decreased after polyaniline coating. The composite under applied magnetic field, exhibited ferromagnetic hysteretic loops with high saturation magnetization ( M S=18.9–3.8 emu/g) and coercivity ( H C=3850.0–583.91 Oe).
