The local spatial and electronic structure of thin films of perovskite-derived LaCoO3-x doped with cerium and tellurium is studied by Co K-edge X-ray absorption spectroscopy (XAS). It is shown that both Ce and Te as dopants give the desired electron-doping effect, and that structural disorder plausibly contributes an important part to the differences in magnetic properties when compared to the hole-doped counterparts.
