dc.description.resumo | High purity BaFe12O19 samples were synthesized by an ionic-coordination-reaction (ICR) technique using chitosan as a complex agent. The mean size Dm of the particles and their magnetic properties were controlled by varying the concentration of chitosan in the starting solution. It was found that Dm, the coercive field Hc, and the Curie temperature Tc decrease when the concentration of chitosan is increased. In addition, the variation of Hc with Dm in these samples can be accounted for using the Stoner–Wolhfarth model. Finally, the magnetic field dependence of the transverse susceptibility were in good agreement with the theoretical predictions of Aharoni et al. [Bull. Res. Counc. Isr. A 6 (1957) 215 | pt_BR |
