Abstract

Modulated structure analysis of the mutually incommensurate composite crystal (Sr2Cu2O3)0.70CuCO2 with two-legged spin ladder has been performed on the basis of (3+1)-dimensional superspace group approach. It has been found that the symmetry of (Sr2Cu2O3)0.70CuO2 should be described by a centrosymmetric superspace group. In the modulated composite structure of (Sr2Cu2O3)0.70CuO2, displacive modulation of O atoms in the CuO2 chain is fairly large and plays an important role. Structural interaction between the CuO2 chain and the Cu2O3 ladder has been extensively investigated.
