Experimental results obtained using Mossbauer spectroscopy (with a radioactive source and a Synchrotron Mossbauer Source) and nuclear forward scattering for a range of different sample compositions in both externally heated and laser-heated diamond anvil cells show clear trends in the variation of hyperfine parameters with pressure and temperature. These trends combined with reported total spin state measurements using X-ray emission spectroscopy on samples of similar composition support the conclusion that Fe2+ undergoes a high-spin to intermediate-spin transition near the top of the lower mantle and an intermediate-spin to low-spin transition near the bottom of the lower mantle. No spin transition is observed to occur in Fe3+ for samples with compositions relevant for the lower mantle."}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1381981469833994116","@type":"Researcher","foaf:name":[{"@value":"Catherine McCammon"}],"jpcoar:affiliationName":[{"@value":"Bayerisches
