Sillen-Aurivillius intergrowth phases as templates for naturally layered multiferroics
The ferroelectric Sillen-Aurivillius phase Bi5PbTi3O14Cl, a layered structure containing three-layer perovskite-type blocks, has been modified by substituting magnetic transition metal cations M3+ = Cr3+, Mn3+, or Fe3+ for1/3 of the Ti4+ cations, accompanied by co-doping of Bi3+ for Pb2+. The aim of the modification was to produce naturally layered ferroelectromagnetic compounds. Rietveld refinements against high-temperature synchrotron X-ray powder diffraction data show that the resulting new...[Show more]
