Phases observed in the BaO−Fe 2 O 3 −TiO 2 system are classified and described in terms of the framework of close‐packed {O,Ba/O} layers, with the transition metal atoms either in octahedral (titanium and iron) or in tetrahedral (iron only) sites. The resulting crystal chemistry features new combinations of structural features intermediate between the magnetic barium hexaferrites and the dielectric barium polytitanates, and thus gives rise to phases with potentially useful magnetic/dielectric properties.
