Unified (3 + 1)-dimensional superspace description of the 2212-type stair-like [Bi2Sr3Fe2O9]m[Bi4Sr6Fe2O16] family of compounds

Popis výsledku v původním jazyce

The (3 + 1)-dimensional superspace approach is applied to describe and refine a series of sheared compounds related to layered high Tc superconducting oxides. Two commensurate members (m = 4, 5) of the 2212 stair-like [Bi2Sr3Fe2O9]m[Bi4Sr6Fe2O16] familyof compounds, previously studied using single-crystal diffraction data, are analyzed. A common average unit cell has been identified and a composition dependent modulation wavevector is proposed. The model is built using only three independent atomic domains, one for the metal atoms and two for the O atoms. The three Sr, Bi and Fe species are described using close-connected crenel-like functions forming a continuous atomic domain along the internal space.
