Effect of Al on the sharpness of the MgSiO_3 perovskite to post-perovskite phase transition [PDF]

open access: yes, 2005
By means of static ab-initio computations we investigate the influence of Al on the recently discovered perovskite to post-perovskite phase transition in MgSiO_3. We examine three substitution mechanisms for Al in the two structures: MgSi → AlAl; SiSiO →
