Abstract

Systematic measurements of magnetic susceptibility and neutron diffraction were performed on both as-grown and oxygen-reduced single crystals of Pr 1-xLaCexCuO4-δ (x = 0.09, 0.11, 0.15 and 0.18) in order to study the electronic phase diagram as functions of both x and δ. Antiferromagnetic ordered phase appears in the x = 0.09 and 0.11 samples for small value of δ at low temperature and degrades by either increasing Ce concentration or δ. Bulk superconductivity was observed in the wider x and δ region compared to that of Nd2-xCe xCuO4. A spin-glass-like phase appears in the limited region of δ in between 0.003 and 0.04, which weakly depends on x. Combining both results from susceptibility and neutron scattering measurement, we have obtained x-δ phase diagram of Pr1-xLaCe xCuO4-δ.
