In this area of the BaO-TiO2-Fe2O3 phase diagram, numerous ternary compounds were found for extremely close chemical and thermal conditions and multilayered phases were always prepared together with a few adjacent phases. The structure of the multilayered compound (Ba42Ti51Fe20O174: space group C2/m; a=9.9512(2) Å, b=17:2366(4) Å, c =
