Abstract

High resolution neutron and x-ray powder diffraction data show that samples of Nd_2−xCe_xCuO₄ are multiphase except at x=O and the optimum superconducting composition x≈0.165. Cerium doped samples with compositions other than x≈0.165 appear to be mixtures of the superconducting phase, which has a fixed composition, and non-superconducting phases with different compositions. The phase separation could result from non-equilibrium behavior during synthesis.
