Article Synopsis
- - The BiTiFeO materials consist of perovskite blocks made up of (001) plane-parallel (Ti,Fe)O octahedra, separated by interfaces that create S-shaped tunnels stabilized by Bi cations.
- - Advanced techniques like transmission electron microscopy and X-ray diffraction reveal various structures (orthorhombic and monoclinic) that vary with the thickness of the perovskite blocks (n = 4-6), affecting atomic displacements and periodicity.
- - The n = 4-6 homologues exhibit strong antiferromagnetic properties at specific temperatures and demonstrate a unique structural diversity, including defects and a high dielectric constant that changes slightly with temperature.
A novel anion-deficient perovskite-based compound, Pb(2.4)Ba(2.6)Fe(2)Sc(2)TiO(13), was synthesized via the citrate-based route.
