• Intermediate-spin ferrous iron in lower mantle perovskite (2007, methodology): “Our low-pressure Mossbauer spectra are similar to those in the literature, and show one broad quadrupole doublet assigned to HS Fe 2+ in the 8–12-coordinated site, and one quadrupole doublet assigned to HS Fe 3+ (refs&nbs”
• Valence state and spin transitions of iron in Earth's mantle silicates (2006, background): “For Pv we find that [Fe–Al] coupled substitutions are favourable, in agreement with previous studies [2,3,8].”
• A synchrotron Mössbauer spectroscopy study of (Mg,Fe)SiO3 perovskite up to 120 GPa (2005, background): “…Jephcoat et al. 1999), atomistic simulations (Richmond and Brodholt 1998), XES (Li et al. 2003), and 57Fe Mössbauer spectroscopy (MBS) under ambient conditions (e.g., Jeanloz et al. 1992; Lauterbach et al. 2000) and at a range of temperatures (McCammon et al. 1992; Fei et al. 1994; McCammon 1998b).”
• Solidus and liquidus profiles of chondritic mantle: Implication for melting of the Earth across its history (2011, background): “Indeed, a higher absorption efficiency for the solid is expected since Al-bearing (Mg, Fe)SiO3 perovskite contains high Fe3+-content (Lauterbach et al., 2000).”
• Water partitioning at 660 km depth and evidence for very low water solubility in magnesium silicate perovskite (2003, methodology): “The relationship between the concentrations of ferric iron and aluminium in perovskite, as determined previously using Mössbauer and EELS spectroscopies [Lauterbach et al., 2000], was used to calculate the content of oxygen vacancies in our samples.”
