Effects of Fe spin transition on the elasticity of (Mg, Fe) O magnesiowustites and implications for the seismological properties of the Earth's lower mantle

Effects of Fe spin transition on the elasticity of (Mg, Fe) O magnesiowustites and implications for the seismological properties of the Earth's lower mantle

High-pressure x-ray diffraction of (Mg0.80 Fe0.20)O at room temperature reveals a discontinuity in the bulk modulus at 40 (±5) GPa, similar to the pressure at which an electronic spin-pairing transition of Fe2+ is observed by Mössbauer spectroscopy. We determine the zero-pressure bulk modulus of low...
