N2 - We report the analytical results of Cu valence and the amount of oxygen deficiency in high Tc superconductors, SrxLa2-xCuO4-y. These results show that for the sample with x=0, the valence state of all Cu ion is proved to be Cu2+. Amount of Cu3+ and oxygen deficiency linearly increase with increasing Sr. According to this, there is no clear correlation between the transition temperature and the oxygen deficiency.
