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.
