Evidence for the charge disproportionation of iron in extraterrestrial bridgmanite
Bridgmanite, MgSiO(3) with perovskite structure, is considered the most abundant mineral on Earth. On the lower mantle, it contains Fe and Al that strongly influence its behavior. Experimentalists have debated whether iron may exist in a mixed valence state, coexistence of Fe(2+) and Fe(3+) in bridg...
