Abstract

We have successfully synthesized a new electron-doped superconducting cuprate Li_xSr₂CuO₂I₂ by the electrochemical Li-intercalation technique. The electrochemical intercalation was carried out at room temperature under a constant potential of 500 mV vs. Li/Li⁺ using a three-elecrode cell. It has been found that Li ⁺ ions tend to be intercalated readily with the increase of the ionic radius of X^- in Sr₂CuO₂X₂ (X = Cl, Br, I). The magnetic susceptibility measurements have revealed the appearance of superconductivity with the superconducting transition temperature T_c = 4.5 K in Li_0.25Sr₂CuO₂I₂, which is lower than T_c = 8.0 K in Li_0.15Sr₂CuO ₂Br₂.
