Postperovskite phase transition and its geophysical implications (2006, methodology): “calculations by Tsuchiya et al. [2004a] showed that the phase transition occurs at 117–127 GPa at 2500 K, consis-”
Post‐perovskite phase transition and mineral chemistry in the pyrolitic lowermost mantle (2005, methodology): “Pressure was determined by applying the equation of state (EOS) of gold recently proposed by Tsuchiya [2003] , using both (111) and (200) lines of gold.”
In situ observations of phase transition between perovskite and CaIrO3-type phase in MgSiO3 and pyrolitic mantle composition (2005, background): “In contrast, Tsuchiya’s EOS of gold [56] is several GPa higher than Jamieson’s EOS.”
Spin state of ferric iron in MgSiO3 perovskite and its effect on elastic properties (2010, methodology): “The glasses were ground to a powder and mixed with 10 wt.% Au for use as an internal pressure standard (Tsuchiya, 2003) for the XRD study.”
