Nanosize magnesium–zinc powders are synthesized by means of the sol–gel autocombustion technology. By means of the X-ray investigation, it is determined the phase composition of the diamagnetically substituted ferrite systems. As shown, the resulting complex-oxide powders are agglomerated and consist of several nanoparticles with an average size of 20–35 nm. The parameters of porous structure depending on the composition of powders are determined. As found for all samples, the nanopores with a radius of about 2 nm make the main contribution to the total volume of pores. As revealed, the pores as cylindrical channels with a diameter of about 5–12 nm permeate agglomerates of particles.
