Structural Study of a Group of Magnetic Multilayered Oxides in the BaO:FE2O3:TiO2 System. Part I: High-Resolution Electron Microscopy


Leonid A. Bendersky, Terrell A. Vanderah, Robert S. Roth


In recent work on phase equilibria relations in the BaO:Fe2o3:Tio2 system, numerous ternary compounds were found. Most of the newly found compounds are complex and exhibit new structural types. The structures of six of these compounds, the so-called E,M,K,N,L and J phases, were characterized by high-resolution electron microscopy. All compounds were shown to belong to a class of ordered intergrowth structures built from two types of alternating slabs related to the structures of hexagonal BaTio (h-BaTio3) and Ba12Fe28Ti15o84(12:14:15), which are in thermodynamic equilibrium with most of the studied phases. All of the phases exhibit close-packed structures built from {o, (Ba/o)} layers in different stacking sequences. The so-called P slab has a structure related to h-BaTio3, in which Ti occupies the octahedral B cation sites. The second type of slab, denoted H, exhibits related but somewhat different structures in the E and M phases (H'), and four other phases (H). The structure of the H' slab is likely related to the spinal block portion of the 12:14:15 compound, whereas the H slab is related to the entire 12:14:15 structure.
