Abstract
The spin ladder system Sr14-xCaxCu24O41 is reviewed from the viewpoint of relations be-tween the crystal structure and superconductivity under high pressure. The compound is a composite crystal, which consists of CuO2 1-D chain and Cu2O3 tow-leg ladder subsystems. As the interplay of the subsystems is increased with Ca substitution or pressurization, holes are removed from the 1-D chain to the ladder via locally formed apical oxygen bonds. Then, the superconductivity occurs owing to the hole doping into the ladder. The hole distribution, magnetic interaction, and electrical property of the normal state are also discussed in terms of the structural modulation.
