概要
- 論文の詳細を見る
We report the analytical results of Cu valence and the amount of oxygen deficiency in high T_C superconductors, Sr_xLa_<2-x>CuO_<4-y>. These results show that for the sample with x=0, the valence state of all Cu ion is proved to be Cu^<2+>. Amount of Cu^<3+> and oxygen deficiency linearly increase with increasing Sr. According to this, there is no clear correlation between the transition temperature and the oxygen deficiency.
