A new mixed metal titanate Ba 3 Fe 24 Ti 7 O 53 , 1 was obtained by heating stoichiometRic mixtures of BaCO 3 , Fe 3 O 4 and TiO 2 to 1375°C for 48 h. Compound 1 was characterized by single crystal x‐ray diffraction analysis. Two of the barium ions lie in a network of channels in the bc crystallographic plane. The iron and titanium atoms were refined in a random distribution in 16 independent MO 6 octahedral sites and 2 MO 4 tetrahedral sites. Magnetization measurements reveal a strong magnetic ordering up to 600 K. M vs. H loop measurements show no hysteresis effects.
