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…
Low thermal conductivity of iron-silicon alloys at Earth core conditions with implications for the geodynamo
Wen-Pin Hsieh, Alexander F. Goncharov, Stéphane Labrosse +5
Earth core is composed of iron (Fe) alloyed with light elements, e.g., silicon (Si). Its thermal conductivity critically affects Earth thermal structure, evolution, and dynamics, a…
Intermolecular coupling and fluxional behavior of hydrogen in phase IV
Alexander F. Goncharov, Irina Chuvashova, Cheng Ji +1
We performed Raman and infrared (IR) spectroscopy measurements of hydrogen at 295 K up to 280 GPa at an IR synchrotron facility of SSRF. To reach the highest pressure, hydrogen was…
