Computer simulations of iron in magnesium silicate perovskite [PDF]

open access: yes, 2008
We use atomistic computer simulation techniques to investigate the site partitioning of iron in (Mg,Fe)SiO_{3} perovskites. Our calculations predict that the most energetically favourable reaction for iron substitution will be a direct exchange of Fe^{2+}
