The comparison between X‐ray resonant scattering experiments and X‐ray absorption data shows that no real Mn 3+ /Mn 4+ charge ordering occurs in manganites with Mn 3+ /Mn 4+ = 1 ratio. However, these experiments demonstrate the presence of two different types of manganese atoms with a different local geometrical structure. A structural model, which accounts for both X‐ray absorption and resonant scattering experiments, is proposed.
