Аннотация: The polycrystalline SrFe12O19 deeply substituted up to at.67% by Al3+, Ga3+, In3+, Co3+, and Cr3+cations with a high configurational mixing entropy were prepared by solid-phase synthesis. Phase purity and unit cell parameters were obtained from XRD and analyzed vs. the average ionic radius of the iron sublattice. The crystallite size varied around ~ 4.5 μm. A comprehensive study of the magnetization was realized in various fields and temperatures. The saturation magnetization was calculated using the Law of Approach to Saturation. The accompanying magnetic parameters were determined. The magnetic crystallographic anisotropy coefficient and the anisotropy field were calculated. All investigated magnetization curves turned out to be nonmonotonic. The magnetic ordering and freezing temperatures were extracted from the ZFC and FC curves. The average size of magnetic clusters varied around ~ 350 nm. The high values of the configurational mixing entropy and the phenomenon of magnetic dilution were taken into account.
