USPEX - Evolutionary crystal structure prediction (2006, background): “was found [17,18] only after an analogous phase was identified for Fe2O3 [19].”
Stagnant slab : A review (2009, background): “Hirose et al. (2005) investigated phase relations, mineral chemistry and density of MORB composition to show that the post-perovskite transition (Murakami et al., 2004; Tsuchiya et al., 2004; Oganov and Ono, 2004) of MORB composition starts at a pressure lower than the transition pressure for pure…”
Phase relations and equation of state of a natural MORB: Implications for the density profile of subducted oceanic crust in the Earth's lower mantle (2010, methodology): “As shown by Murakami et al. [2004] and Ono and Oganov [2005], the density increase in Mg‐perovskite associated with this transition is most likely to be up to 1%. As the proportion of magnesium perovskite in MORB is about 40%, we would obtain a total increase in MORB density of about 0.4%.”

Energetics of the Core (2015, background): “Because this phase transition occurs at particular P, T conditions (Murakami et al. 2004, Oganov and Ono 2004), seismic detection of the depth of the transition provides a temperature constraint.”
Postperovskite phase transition and its geophysical implications (2006, methodology): “[9] Phase transition of MgSiO3 perovskite was discovered through a significant change in the XRD pattern (Figure 1) [Murakami et al., 2004].”
The effect of temperature on the seismic anisotropy of the perovskite and post-perovskite polymorphs of MgSiO 3 (2004, background): “The effect of temperature on the acoustic properties of the newly discovered post-perovskite phase [36–38] is also thoroughly investigated and compared with those determined from high-pressure athermal calculations [39,40].”
Dynamics and evolution of the deep mantle resulting from thermal, chemical, phase and melting effects (2012, background): “The phase transition from perovskite to post-perovskite was discovered in 2004 (Murakami et al., 2004; Oganov and Ono, 2004; Tsuchiya et al., 2004a) and is interesting in the present context for two reasons: its influence on the dynamics, and its ability to explain various seismological…”
