Mang et al. observe a cubic (Nd,Ce)2O3 impurity phase grown epitaxially in annealed samples of electron-doped Nd2-xCexCuO4 (NCCO). They claim that this impurity phase has long-range order parallel to the CuO2 planes of NCCO but extending only about 4ac perpendicular to the planes, thus forming a quasi-two-dimensional (Nd,Ce)2O3 lattice matched with the a–b plane of NCCO.
