Abstract
Abstract—We have studied the effect of Sc3+ substitution for Fe3+ ions on the magnetic properties and crystal structure of BaFe12– xScxO19 hexaferrites. Based on Mossbauer spectroscopy data, we have assessed the distribution of scandium ions over sublattices and their effect on magnetic characteristics of the materials. The specific magnetization and coercive force of the ferrites have been shown to depend on the location and concentration of scandium ions in the crystal structure. The hexaferrite with x > 0.6 has been found to have a noncollinear magnetic structure.
