Iron oxides are among the major constituents of the deep Earth's interior. Among them, the
epsilon phase of Fe2O3 is one of the less studied polymorphs and there is a lack of …

There are still large discrepancies among the previous reports on the spin transition of iron
in Mg–perovskite (Pv). To alleviate this problem, we examined the spin state of Fe3+ in Mg0 …

We have investigated the electronic configuration of iron in Fe-, Al-containing magnesium
silicate perovskite, ie, bridgmanite, the main component of the lower mantle, at conditions of …

We present a review of our recent work concerning the spin state of Fe2+ and Fe3+ in iron
magnesium aluminium silicate perovskite, the most abundant phase in the Earth's interior …

Abstract Spin transitions in (Mg, Fe) SiO3 bridgmanite have important implications for the
chemistry and dynamics of Earth's lower mantle, but have been complex to characterize in …

Abstract δ-AlOOH has emerged as a promising candidate for water storage in the lower
mantle and could have delivered water into the bottom of the mantle. To date, it still remains …

Mg1-x Fex SiO3 (Synthesized Under Pressure) Page 1 Mg1-x Fex SiO3 (Synthesized Under
Pressure) The orthorhombic perovskite MgSiO3 (x ¼ 0) was synthesized at about 280 kbar …

As an important and matured experimental technology to probing materials' structure,
synchrotron radiation attracts huge amount of users including condensed-matter physicists …

Extremely high P–T conditions in the lower mantle affect some basic physicochemical
properties of elements in minerals. One of the most important is a spin transition, which …

Untersuchungen unter extremen Bedingungen sind ein wichtiges Hilfsmittel bei der
