Abstract: Planar shock compression experiments are performed at 9–105 GPa on polycrystalline ferropericlase (Mg0.94Fe0.06)O to investigate its Fe2+ spin transition. Forward and reverse impact configurations are used to obtain Hugoniot and shock-state sound velocities. While wave… read more here.

Abstract: Ferropericlase (Fp), $({\mathrm{Mg}}_{1\ensuremath{-}x}{\mathrm{Fe}}_{x})\mathrm{O}$, is the second most abundant phase in the Earth's lower mantle. At relevant pressure-temperature conditions, iron in Fp undergoes a high spin (HS), S = 2, to low spin (LS), S =… read more here.
