Evidence from the paper
On the other hand, a static compression study on single-crystals of (Mg0.725Fe0.268[]0.007)O, (Mg0.423Fe0.541[]0.036)O, and (Mg0.211Fe0.762[]0.027)O to ~9 GPa produces values of K'T0 ≅ 5.5 ± 0.2, with the possibility that this high value reflects the behavior of less-stoichiometric (Mg,Fe)O [Jacobsen et al., 2002].
