Abstract

We report the synthesis of a new series of layered copper oxide compounds, Nd_2-x-yA_xCe_yCuO_4-δ (Ag^II Mg and Ca), which are isostructural with the T′-phase of the superconducting, n-type Nd_2-xCe_xCuO_4-δ. An extended solid solubility range, x + y ≤ 0.60, is observed. The as-prepared air-quenched samples show semiconducting behavior. These newly prepared compounds raise further questions about electron-doped superconductivity in the cuprate oxides.
