The self-diffusion coefficients (D_Fe and D_Ni) of Fe and FeNi fluid under Earth's core conditions. (a) is along the core adiabatic, and (b) is temperature variation at CMB and ICB. ‘Wijs’¹⁸, ‘Alfe’⁸, ‘Pozzo1′⁹, ‘Pozzo2′⁹ and ‘Pozzo3′⁹ represent the self-diffusion coefficient of Fe in Fe, Fe_0.82Si_0.10O_0.08 and Fe_0.79Si_0.08O_0.13 fluids.
