Evidence from the paper

Our results agree with the recent investigation by Fei, but not with that by Zhang. In the latter study, the bulk modulus of Fe0.99O is much higher, 175 GPa. A sudden increase in the bulk modulus of Fe1-xO from an almost constant value of 150 GPa for an iron-poor sample is suggested at around Fe0.98O.
