  Based on the digitized electron micrographs, we investigate a temperature
evolution of Co/C film. The simple in usage quantitative characterization of
the spatial disorder for systems of point objects has been employed. We show
that a dominant increase of spatial inhomogeneity of cobalt phase is shifted
towards the larger length scales along the sample heating temperature. The
results allow the subtle differences of spatial inhomogeneity in thin metallic
films to be explored.
