Abstract : A study was made of the effect of admixtures of lanthanum, cerium and yttrium oxides on the magnetic characteristics of manganese and magnesium-manganese ferrites. This effect differs for various rare-earth elements and depends on their content in the ferrite. The fine structure of the X-ray absorption spectra of iron and manganese in ferrites with various quantities of additions of rare-earth elements was investigated. On the basis of an analysis of the experimental data inferences were drawn as to the possible mechanism of the effect of admixtures on the energetic state of the atoms of the basic components in the ferrites.
