Abstract
A mixture of ferrites phases containing strontium ortho/hexagonal ferrites was synthesized using chitosan as template and heat treatments. The analysis by XRD, FTIR, SEM, TEM and HRTEM showed the coexistence of the perovskite-like SrFeO2.9 and hexaferrite SrFe12O19 phases. The ferrites consisted of hard agglomerates containing nanoparticles. The crystallites sizes range between 5 and 20Â nm of different morphologies. A possible phase transition model is suggested.
