Low-spin ferrous iron suppresses mantle oxidation beyond Earth-like pressures

Alice Girani, Sylvain Petitgirard, Sergey Yaroslavstsev +5

The Earth's mantle has elevated Fe relative to those of other rocky bodies, yet the oxidation- and electronic state of iron at extreme pressures is poorly known. We present…
