Fig. 4: Selected synchrotron Mössbauer source spectra of various phases of Fe0.94O at indicated pressures and room temperature.
From: Monoclinic distortion and magnetic transitions in FeO under pressure and temperature
For the crystallographic description of the phases please refer to the main text. Solid lines show the model fits, the percentage bars in all panels indicate the relative absorptions, and the residuals of the fits are indicated below each spectrum (a–f). Sextet with an exponential distribution of the magnetic field is used to fit the magnetic component above 80 GPa (e, f).
