The realization of oxygen over stoichiometry through oxidation of Co2+ into Co3+ in the 2H-perovskite related oxides Sr1+x(Mn1−xCox)O3 is demonstrated, leading to a large family of cation deficient Ising chain oxides Sr1+y[(Mn1−xCox)1−z□z]O3.

We report the possibility of extending the so-called stairlike Aurivilius phases in the pseudobinary Bi5Nb3O15-ABi2Nb2O9 (A = Ba and Sr) over a wide range of compositions. These phases are characterized by a discontinuous stacking of [Bi2O2] slabs an
