Auxiliary material for this article contains a text file describing sample characterization; determination of the spin crossover from experimental data and derivation of the thermal EoS parameters; and pressure and temperature dependence of the LS fraction, thermal expansion coefficient, isothermal bulk modulus, and bulk sound velocity along a lower-mantle geotherm, as well as three figures showing the representative X-ray diffraction patterns of ferropericlase in a laser-heated DAC at high pressures and temperatures, the fraction of the LS state in ferropericlase along a mantle geotherm, and the thermal elastic parameters of ferropericlase at constant temperatures derived from our experimental results and a table containing the experimental obtained unit cell volume of ferropericlase at a given temperature.
Auxiliary material files may require downloading to a local drive depending on platform, browser, configuration, and size. To open auxiliary materials in a browser, click on the label. To download, Right-click and select “Save Target As…” (PC) or CTRL-click and select “Download Link to Disk” (Mac).
