   The temperature dependence of magnetic susceptibility χ(T) is very suitable tool for the identification of magnetic phases into the ferrites and their Curie temperatures T_C. The initial susceptibility measured data offer qualitative and partly quantitative analysis of different types of magnetic materials. It is possible to determine the oxidation state, morphological and chemical features of materials.

Keywords: susceptibility, magnetic moment, Curie temperature, ferrites, annealing temperature
