AbstractThe α-Fe2O3 nanoparticles have been synthesized using some surfactants in micro-emulsion method. Magnetization, M (H), of samples was measured at room temperature. Magnetic hysteresis loops were observed in all samples. A new magnetization function (H - A model) was offered to explain the field dependence of the magnetization behavior of α-Fe2O3. In this work, the magnetization curve of all samples was analyzed based on MBrillouin, MBrillouin-Akulov, and MBrillouin-(H - A) model. The experimental data have fitted with the MBrillouin-(H - A) model, and the best fitting parameters were analyzed.
