The mechanically induced changes in structure and magnetic properties of zinc ferrite were investigated by using the Rietveld analysis and Mössbauer spectroscopy. The formation of the spin arrangement in mechanically activated zinc ferrite is connected with a redistribution of the cations in the close‐packed anionic sublattice. On the basis of the Rietveld analysis the degree of mechanically induced inversion as well as the exact coordinates of atoms and lattice parameters in non‐activated and mechanically activated ZnFe 2 O 4 was determined.
