Composition and state of the core
The composition and state of Earth's core, located deeper than 2,900 km from the surface,
remain largely uncertain. Recent static experiments on iron and alloys performed up to inner …

PBE-GGA predicts the B8↔ B2 phase boundary of FeO at Earth's core conditions
FeO is a crucial component of the Earth's core, and its thermodynamic properties are
essential to developing more accurate core models. It is also a notorious correlated insulator …

Experimental and Theoretical Evidence for Pressure-Induced Metallization<? format?> in FeO with Rocksalt-Type Structure
Electrical conductivity of FeO was measured up to 141 GPa and 2480 K in a laser-heated
diamond-anvil cell. The results show that rock-salt (B1) type structured FeO metallizes at …

Sound velocity and density of magnesiowüstites: Implications for ultralow‐velocity zone topography
JK Wicks, JM Jackson, W Sturhahn… - Geophysical Research …, 2017 - Wiley Online Library
We explore the effect of Mg/Fe substitution on the sound velocities of iron‐rich (Mg1− xFex)
O, where x= 0.84, 0.94, and 1.0. Sound velocities were determined using nuclear resonance …

Viscosity jump in the lower mantle inferred from melting curves of ferropericlase
Convection provides the mechanism behind plate tectonics, which allows oceanic
lithosphere to be subducted into the mantle as “slabs” and new rock to be generated by …
