Figure 3.7.1

A plot generated by the Results/Graph Fields function in the Powder Diffraction File. The search was for entries containing only Fe and O and with space group No. 225 (resulting in FeO entries) measured under ambient conditions. One outlier was removed from the hit list manually. The trend in the cubic a lattice parameter with Fe content is apparent, as well as the large number of apparently stoichiometric FeO entries, some of which may not be correctly characterized.
