Abstract

Samarium‐based oxyfluoride analogs of the apparently “n‐type” 24 K superconductor, Nd1.85Ce0.15CuO4, were prepared. A series of compounds with general formula Sm2‐xCexCuO4‐yFy were prepared and characterized by X‐ray diffraction, bromo/iodometric titration, and measurements of electrical resistivity. Homogeneous superconducting phases have not yet been obtained; preliminary results and discussion of property trends are presented.
