N2 - Magnetic-cation-doped three-layer Aurivillius phases Bi 2-xSr2+x(Nb/Ta)2+xM1-xO 12, x≈ 0.5 and M = Ru4+, Ir4+ or Mn 4+, are shown to have the same orthorhombic space group symmetry and similar dielectric and ferroelectric properties as their (non-magnetic) ferroelectric parent compounds Bi2-xSr2+xNb 2+xTi1-xO12, x = 0, 0.5. The magnetic-cation-doped phases also show evidence for short-range ferromagnetic (M = Mn) and antiferromagnetic (M = Ru and Ir) exchange, demonstrating the potential of these naturally layered phases as templates for multiferroic (magnetoelectric) materials.
