Volume Collapse Without a Structural Transition in Shock-Compressed FeO
C. Crépisson, T. Stevens, M. Fitzgerald +121
We report x-ray diffraction and emission spectroscopy of FeO under laser-driven shock compression between 31-199 GPa. FeO retains the B1 (rocksalt) structure along the Hugoniot to…

Iron spin crossover in ferropericlase and its effect on lower-mantle thermal conductivity
Alexander F. Goncharov, Irina Chuvashova, Eric Edmund +29
Thermal conductivity of Earths lower mantle controls heat transfer across the core-mantle boundary (CMB) and strongly influences mantle convection. We report direct measurements of…

High-Quality Ultra-Fast Total Scattering and Pair Distribution Function Data using an X-ray Free Electron Laser
Adam F. Sapnik, Philip A. Chater, Dean S. Keeble +48
High-quality total scattering data, a key tool for understanding atomic-scale structure in disordered materials, require stable instrumentation and access to high momentum transfer…
