A new manganese oxide with the Aurivillius structure: Bi2Sr2Nb2MnO12−δ

A New Bi4Mn1/3W2/3O8Cl Sillén–Aurivillius Intergrowth: Synthesis and Structural Characterisation by Quantitative Transmission Electron Microscopy

“…Table 4 summarises the refined structural parameters; the R factors of weighted pattern (R wp ), pattern (R p ) and Bragg (R B ) converge to 16.1 %, 12.9 % and 5.87 % respectively. These values agree with those obtained in other Aurivillius [19,20] and Sillén-Aurivillius [8] phases. It is worth mentioning that the high B value obtained for Bi (2) in the refinement agrees with our previous work on the isostructural Bi 4 Ti 1/2 W 1/2 O 8 Cl compound.…”

Aurivillius phases of PbBi4Ti4O15 doped with Mn3+ synthesized by molten salt technique: Structure, dielectric, and magnetic properties

“…Therefore, high pressure is the only known method to prepare monoclinic BiMnO 3 [7]. Some Aurivillius phases containing both Ti 4 þ or Nb 5 þ and Mn 3 þ cations synthesized by solid-state reaction have been reported [9][10][11][12][13]. However, the presence of impurities in the samples was a common problem in all of these studies.…”

“…There are also conflicting reports on the Aurivillius phases prepared by conventional solid state reaction. For example, Yu et al [9] reported that they successfully prepared Bi 2 Sr 2 Nb 2 MnO 12 À d , but McCabe and Greaves [10] cannot prepare this compound by the same method. Furthermore, Kumar et al [11] and Suresh et al [12] have reported the synthesis of Bi 5 Ti 3 MnO 15 and Bi 6 Ti 3 Mn 2 O 18 , respectively, by solid state reactions.…”
