Abstract

The effect of Bi doping on the modulated composite structure of (Sr₂Cu₂O₃)_0.70CuO₂ has been extensively investigated on the basis of (3+1)-dimensional superspace group approach. By applying the bond-valence-sum method for the modulated composite structure, it has become apparent that the valence state of the Cu atom in any sites of the Cu₂O₃ ladder in (Sr_2-xBi_xCu₂O₃)_0.70CuO ₂ is maintained divalent. The interatomic distance between the Cu atom in the two-legged Cu₂O₃ ladder and the O atom in the CuO₂ chain becomes larger with Bi doping, in spite of the slight shrinkage of lattice dimension along the stacking direction. The hole transfer from the CuO₂ chain to the Cu₂O₃ ladder in (Sr₂Cu₂O₃)_0.70CuO₂ is depressed by the effect of Bi doping on the atomic modulations.
