Abstract
Anisotropic characteristics of substituted ferrimagnetics are studied on the basis of BaFe12O19. The constants of Fe3+ ion level splitting by fields with axial symmetry at various crystallographic sites are calculated in the framework of a single-ion anisotropy model. The iron cations at pseudotetrahedral sites 4e·1/2 are shown to have a dominating role in forming magnetic crystalline anisotropy of hexagonal ferrimagnetics with the M-type structure. Magnetic elastic properties of the substituted BaSc-M compound are examined. The possibility of selecting a ferrimagnetic chemical composition with prescribed magnetic properties using mathematical modeling of the main magnetic features of a hypothetical compound is discussed.
