Abstract
In this work SrFe12O19 is synthesised by gel self-propagating combustion technique with glycol as solvent. The morphology, crystal structure and magnetic properties of the as fabricated powders are investigated with X-ray diffraction, field emission scanning electron microscopy, thermogravimetric analysis/differential scanning calorimetry and vibrating sample magnetometry. The results show that the coercivity and specific saturation magnetisation of the as fabricated SrFe12O19 are increased to 528 kA m−1 and 59·6 EMU g−1, in comparison with 404 kA m−1 and 57·6 EMU g−1 using water as solvent. The 528 kA m−1 is the highest Hc value recorded for isotropic SrFe12O19.
