Abstract
Conditions for high-pressure synthesis were examined for defect-type perovskite Ca1-x Sr x CuO2 with planar [CuO2]∞ sheets. For x=0.2, the temperature of preparation ranges from 800°C to over 1000°C at 6 GPa, whereas it falls to around 800°C for SrCuO2. The lattice parameters increase linearly with increasing x.Keywords
