Abstract

The modulated structure of single composite crystal, (Sr₂Cu₂O₃)_0.70CuO₂, "Sr₁₄Cu₂₄O₄₁" with two-legged Cu₂O₃ ladder and one dimensional CuO₂ chain has been investigated by means of the X-ray diffraction method and (3 + 1)-dimensional superspace group approach. The model of the modulated composite structure of (Sr₂Cu₂O₃)_0.70CuO₂ with centrosymmetric superspace group has been compared with the model with acentric superspace group. By considering all of the Sr-O lengths and the magnitude of their modulation amplitudes, it has been deduced that the atomic modulation waves with centrosymmetric symmetry are more significant for the modulated structure of (Sr₂Cu₂O₃)_0.70CuO₂ than the waves with acentric symmetry.
