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 …

Recent progress in simulations of the paramagnetic state of magnetic materials
IA Abrikosov, AV Ponomareva, P Steneteg… - Current Opinion in Solid …, 2016 - Elsevier
We review recent developments in the field of first-principles simulations of magnetic
materials above the magnetic order–disorder transition temperature, focusing mainly on 3d …

Superionic iron alloys and their seismic velocities in Earth's inner core
Earth's inner core (IC) is less dense than pure iron, indicating the existence of light elements
within it. Silicon, sulfur, carbon, oxygen and hydrogen have been suggested to be the …

Possible thermal and chemical stabilization of body-centred-cubic iron in the Earth's core
The nature of the stable phase of iron in the Earth's solid inner core is still highly
controversial. Laboratory experiments suggest the possibility of an uncharacterized phase …

Body-centered cubic iron-nickel alloy in Earth's core
Cosmochemical, geochemical, and geophysical studies provide evidence that Earth's core
contains iron with substantial (5 to 15%) amounts of nickel. The iron-nickel alloy Fe0. 9Ni0. 1 …

Phase relations in the Fe–FeSi system at high pressures and temperatures
RA Fischer, AJ Campbell, DM Reaman… - Earth and Planetary …, 2013 - Elsevier
The Earth's core is comprised mostly of iron and nickel, but it also contains several weight
percent of one or more unknown light elements, which may include silicon. Therefore it is …

Another look at the core density deficit of Earth's outer core
OL Anderson, DG Isaak - Physics of the Earth and Planetary Interiors, 2002 - Elsevier
A constraint adopted in several geochemical studies of core composition is that the core
density deficit (cdd) is 10%, with the implication that this number is based on robust …

A Middle Miocene hominoid from Thailand and orangutan origins
The origin of orangutans has long been debated. Sivapithecus is considered to be the
closest ancestor of orangutans because of its facial–palatal similarities, but its dental …

The Fe-FeSi phase diagram at Mercury's core conditions
Mercury's metallic core is expected to have formed under highly reducing conditions,
resulting in the presence of significant quantities of silicon alloyed to iron. Here we present …

Iron-rich Fe–O compounds at Earth's core pressures
Oxygen and iron are the most abundant elements on Earth, and their compounds are key
planet-forming components. While oxygen is pervasive in the mantle, its presence in the …
