The paper analyzed the crystal structure of ferrite-garnets and it shows the presence of cavities, volume of which is comparable with the volume of the atoms in the lattice. It is shown that the displacement of some cations can lead to changes in the Fourier components of polarizability values by up to 7%. The calculation of Fourier components of polarizability with the displacement of various cations in the crystal lattice cavities conducted in the paper.
