Packing the Core The packing and arrangement of atoms in Earth's solid inner core can dictate processes such as core growth and rotation. Seismology and modeling suggest the inner core is composed primarily of iron, but the structure is less clear due to anisotropic splitting of seismic waves. Tateno et al. (p. 359) performed static compression experiments on pure iron at the extremely high pressures and temperatures found in the inner core and saw that iron prefers a hexagonal close-packed… Expand

Oxygen-driven enhancement of electron correlation in hexagonal iron at Earth's inner core conditions
Earth’s inner core consists of mainly iron with a bit of light elements. Understanding of its structure and related physical properties has been elusive for both experiment and theory due to itsExpand
Crystal structure of iron at the center of the Earth
The inner core, most remote part of our planet, is composed of solid iron. Because the relevant ultrahigh pressure and temperature conditions were only accessible by dynamical shock-wave compressionExpand
Low viscosity of the Earth’s inner core
It is shown by first-principles molecular dynamics that the body-centered cubic phase of iron, recently demonstrated to be thermodynamically stable under the inner core conditions, is considerably less elastic than the hexagonal phase. Expand
Viscosity of hcp iron at Earth’s inner core conditions from density functional theory
It is shown that dislocation creep is a key mechanism driving deformation of hcp iron at inner core conditions, and the associated viscosity agrees well with the estimates from geophysical observations supporting that the inner core is significantly less viscous than the Earth’s mantle. Expand
Toward a mineral physics reference model for the Moon’s core
The results indicate that the seismic velocities proposed for the Moon’s inner core by a recent reanalysis of Apollo seismic data are well below those of γ-Fe, which provides strong constraints to seismic models of the lunar core and cores of small telluric planets. Expand
Melting of Iron at Earth’s Inner Core Boundary Based on Fast X-ray Diffraction
Hot Enough to Melt Iron Earth's core is divided into a fluid outer core and a solid inner core, both composed predominately of iron at extremely high pressures and temperatures. The boundary betweenExpand
Phase Transition of FeO and Stratification in Earth’s Outer Core
From x-ray diffraction measurements of iron monoxide at high pressure and temperature, it is shown that sodium chloride–type FeO transforms to a cesium chloride-like phase above 240 gigapascals at 4000 kelvin with 2% density increase. Expand
High‐Pressure Deformation of Iron–Nickel–Silicon Alloys and Implications for Earth’s Inner Core
Earth’s inner core exhibits strong seismic anisotropy, often attributed to the alignment of hexagonal close-packed iron (hcp-Fe) alloy crystallites with the Earth’s poles. How this alignmentExpand
Stabilization of body-centred cubic iron under inner-core conditions
The Earth’s solid core is mostly composed of iron. However, despite being central to our understanding of core properties, the stable phase of iron under inner-core conditions remains uncertain. TheExpand
Light elements in the Earth’s core
Constraining the core’s composition is essential for understanding Earth accretion, core formation and the sustainment of Earth’s magnetic field. Earth’s outer and inner core exhibit a densityExpand


Elasticity of iron at the temperature of the Earth's inner core
First-principles calculations of the structure and elasticity of dense hexagonal close-packed iron at high temperatures find that the axial ratio c/a of h.c.p. iron increases substantially with increasing temperature, and a simple model of polycrystalline texture in the inner core is combined to account for seismological observations of inner-core anisotropy. Expand
Lopsided Growth of Earth's Inner Core
It is proposed that the growth of the solid core implies an eastward drift of the material, driven by crystallization in the Western Hemisphere and melting in the Eastern Hemisphere, which generates an asymmetric distribution of sizes of iron crystals, which grow during their translation. Expand
High-Pressure Elasticity of Iron and Anisotropy of Earth's Inner Core
A forward model of the inner core based on the predicted elastic constants and the assumption that the innercore consists of a nearly perfectly aligned aggregate of hcp crystals shows good agreement with seismic travel time anomalies that have been attributed to inner core anisotropy. Expand
Stability of the body-centred-cubic phase of iron in the Earth's inner core
The results of molecular dynamics simulations of iron based on embedded atom models fitted to the results of two implementations of density functional theory found that both point to the stability of the body-centred-cubic iron phase at high temperature and pressure. Expand
Body-Centered Cubic Iron-Nickel Alloy in Earth's Core
The experimental and theoretical results suggest that iron alloys with geochemically reasonable compositions (that is, with substantial nickel, sulfur, or silicon content) adopt the bcc structure in Earth's inner core. Expand
Temperature and composition of the Earth's core
The Earth's core is a ball of swirling hot metal at the centre of our planet, with a radius roughly one half of the Earth's radius. It is formed by two parts: a solid inner core, with a radius ofExpand

Hemispherical anisotropic patterns of the Earth’s inner core
It is shown that the data collected are in good agreement with the presence of two anisotropically specular east and west core hemispheres, compelling evidence for the existence of a body-centered-cubic Fe phase at the top of the Earth’s inner core. Expand
