چکیده
|
The 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 mbriiiouin-(h - a) model. the experimental data have fitted with the mbrillouin-(h - a) model, and the best fitting parameters were analyzed.
