The paper discussed the mechanism of formation of polycrystalline hexagonal barium ferrite. The influence of alloying elements on the location of Fe3 hexagonal block R, on the border of hexagonal and spinel blocks (RS). It is shown that the presence of weakly diamagnetic ions or dopants in these positions provides specific properties of hexagonal ferrites and their practical use.
