Abstract

An electrochemical technique was applied to reduce the insulating as-grown Nd_1.85Ce_0.15CuO_4+δ samples. We succeeded in preparing the superconducting sample with T_c ∼ 15 K for the first time. We identified several reactions in the electrochemical reduction processes using cyclic voltammetry measurements. The superconducting properties of samples treated under different electrochemical conditions are reported.
