Abstract :
By means of X-ray diffraction and Mössbauer methods ferrite nanopowders compositions Mg1-xZnxFe2O4 (x = 0, 0.2, 0.44, 0.5, 0.6)with a spinel structure, obtained by the method of sol-gel autocombustion were investigated. It is shown that in single-phase system structural heterogeneity are encountered that arise in the formation of solid solutions of ferrites of various compositions. Structural components arise at the substitution of magnesium by zinc with a relatively high content of paramagnetic iron ions. This is evidenced abnormally strong effective fields at the nuclei. This effect is not observed during the synthesis of ferrites by ceramic technology.
