Thanks to the development of experimental high-pressure techniques and methods for
crystal-structure prediction based on quantum mechanics, in the past decade, numerous …

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 …

Investigating electronic structure and excitations under extreme conditions gives access to a
rich variety of phenomena. High pressure typically induces behavior such as magnetic …

We have performed a series of experiments to investigate the compositional effect on the
compression behavior of (Mg, Fe) O solid solutions at high pressure. The in‐situ synchrotron …

The two widely accepted mechanisms of the insulator-metal Mott–Hubbard transitions which
have been considered up until now are driven by the band-filling or bandwidth effects. We …

The discovery of a pressure induced iron-related spin crossover in Mg (1-x) Fe x O
ferropericlase (Fp) and Mg-silicate perovskite, the major phases of Earth's lower mantle, has …

The thermal equation of state of ferropericlase [(Mg0. 75Fe0. 25) O] has been investigated
by synchrotron X‐ray diffraction up to 140 GPa and 2000 K in a laser‐heated diamond anvil …

Diamond is an evidence for carbon existing in the deep Earth. Some diamonds are
considered to have originated at various depth ranges from the mantle transition zone to the …

Spin state transitions and intermetallic charge transfers can essentially change material
structural and physical properties while excluding external chemical doping. However, these …

Ferropericlase,(Mg, Fe) O, is the second-most abundant mineral of Earth's lower mantle.
With increasing pressure, the Fe ions in the material begin to collapse from a magnetic to …
