Abstract. The Resonant Nuclear Scattering has revealed the directional order that forms in the ferrites due to anisotropic distribution of Fe2+ and Fe3+ to the local direction of magnetization. We undertook to conduct a study on ferrites of composition.The spectra were made on two kinds of samples: quenched and slowly cooled at different temperatures. The results show that it is possible to possible to distinguish at least three sites according to the values of x: an octahedral site (O) occupied by the Fe3+ ion, which will be designated by (Fe3+)O, a tetrahedral site (T) or (Fe2+)T, and a tetrahedral site (T) or (Fe3+)T. The variation of intensity of the site (Fe3+)O according to x, and the differences of variation according to the cooling conditions suggest the existence of a partial order among the nearest neighbours of the site (Fe3+)O of an ion (Fe3+)T, which will make good account of the directional order.
