A Relative of Sr4Fe6O13 with Double Perovskite Layers: Bi4Sr14Fe24O56,
m = 2-Members of a Potential Series [(Sr,Bi)2Fe 4O7-δ][(Sr,Bi)2Fe2O6]m. — The new
title ferrite is obtained from a stoichiometric mixture of Bi2O3, Fe2O3, and SrO
(1100 °C, 48 h) and characterized by XRD and HREM. The modulated structure of the
compound consists of an intergrowth of double perovskite layers [(Sr,Bi)2Fe2O6] with
oxygen-deficient [(Sr,Bi)2Fe4O7-δ] layers which are built up of FeO5 bipyramids and
distorted tetragonal pyramids. The potential title series offers a great possibility of cationic and oxygen nonstoichiometry, in connection with the structure modulation. —
