We have critically reviewed and discussed currently available information regarding the spin
and valence states of iron in lower mantle minerals and the associated effects of the spin …

Mantle minerals at shallow depths contain iron in the high-spin electronic state. The crystal-
field splitting energy increases with increasing pressure, which can favor the low-spin state …

Using density functional theory plus Hubbard U calculations, we show that the ground state
of (Mg, Fe)(Si, Fe) O 3 perovskite, the major mineral phase in Earth's lower mantle, has high …

Recent studies have indicated that a significant amount of iron in MgSiO3 perovskite (Pv) is
Fe3+ (Fe3+/ΣFe= 10–60%) due to crystal chemistry effects at high pressure (P) and that …

The thermal conductivity of the lowermost mantle controls the energy transfer from the core
to the mantle, and provides insight into the thermal history, evolution, and magnetic field of …

Complex seismic, thermal, and chemical features have been reported in Earth's lowermost
mantle. In particular, possible iron enrichments in the large low shear‐wave velocity …

We present local density approximation augmented by the Hubbard‐type correction
calculations of high‐temperature elastic properties of bridgmanite with composition for …

We have measured the effects of the coupled substitution of Fe3+ and Al on the density and
compressibility of mantle silicate perovskite (Pv) up to 95GPa. X-ray emission spectroscopy …

With local density approximation+ Hubbard U (LDA+ U) calculations, we show that the
ferromagnetic (FM) insulating state observed in tensile-strained LaCoO 3 epitaxial thin films …

Face centered cubic (fcc) FeHX was synthesized at pressures of 18–68 GPa and
temperatures exceeding 1,500 K. Thermally quenched samples were evaluated using …
