Abstract

A combined single-crystal inelastic x-ray scattering (IXS) and x-ray diffraction (XRD) study of synthetic wüstite Fe0.95 O at elevated pressure revealed an increasing difference in the bulk modulus determined from static XRD and dynamic IXS measurements upon compression. We explain this observation by anelastic relaxation in the studied material and propose a model for the quantitative description of such a physical phenomenon. The analysis of available data provides evidence for a reasonably good agreement for bulk moduli and a systematic difference for their pressure derivatives between static and dynamic measurements.
