概要
- 論文の詳細を見る
Conditions for high-pressure synthesis were examined for defect-type perovskite Ca_<1-x>Sr_xCuO_2 with planar [CuO_2]∞ sheets. For x=0.2, the temperature of preparation ranges from 800℃ to over 1000℃ at 6 GPa, whereas it falls to around 800℃ for SrCuO_2. The lattice parameters increase linearly with increasing x.
