Abstract
Sr-doped Pr1.85Ce0.15CuO4+δ samples have been prepared with accurate control of the oxygen content. The stability of both T′ and T* phases is strongly dependent on Sr and oxygen content. An electron diffraction study indicates that, in some cases, anionic vacancies are ordered leading to a pseudo-tetragonal superlattice with unit cell parameters . Structural transitions and superconducting phases created by hole doping in such a system are also reported.
