Does the LaMnO3 phase accept Ce-doping?

Recent reports, that the samples of nominal compositions, La1-xCexMnO3, form single-phase compounds with orthorhombically distorted perovskite structure, are questionable. Our studies on the sample of nominal composition, La0.7Ce0.3MnO3, and careful analysis of the structural data available in the literature, suggest that the above mentioned samples actually form multi-phase mixtures comprising hole doped lanthanum deficient lanthanum manganate phases and cerium oxide (CeO2).
