Evidence from the paper
"Yutani et al. [1997] obtained K0 = 241 GPa (assuming K0' = 4) for the CaFe2O4 phase of MgAl2O4. They applied synchrotron-based X ray diffraction, as in the present study, using a fluid pressure medium so that the data were unaffected by nonhydrostaticity. Their pressure range was limited to 9 GPa."
Additional notes
note
Present study finds Yutani et al. data generally compatible with a curve based on K0 = 210 GPa and K0' = 4 through this study's data
