Abstract in another language

The incommensurate, modulated crystal structures of Sr1+x(CoxMn1-x)O3 (x ≈ 0.266 and 0.280) have been refined by a (3+1)D superspace profile analysis of neutron powder diffraction data. The structures are related to the 2H perovskite structure and consist of two subsystems, [CoxMn1-xO3]∞ chains containing face-sharing MnO6 octahedra and CoO6 trigonal prisms (albeit with some cation site inversion), separated from each other by [Sr]∞ chains. The observed structures are closely related to those expected for the idealized compositions Sr14Co3Mn8O33 and Sr9Co2Mn5O21. Both of the compositions investigated show hysteresis in their magnetic behavior below 13 K.
