Figure 5
Left: normalized volume–pressure data for cubic and rhombohedral phases of Fe0.93O (filled symbols) with fitted equations of state (solid lines). Variation of the c/a ratio with pressure (filled circles) is shown on the right. The equation of state of the rhombohedral phase was determined first by fitting the high-pressure data to a 28 GPa reference pressure, and then back-calculating V0, K0 and K′. Direct fitting of the P–V data (without a P0 data point) yields consistent equation-of-state parameters (see text for details). Error bars are within the size of the symbols.
