Fe-FeH Eutectic Melting Curve and the Estimates of Earth's Core Temperature and Composition

Shuhei Mita, Shoh Tagawa, Kei Hirose +1

Fe and FeH form a binary eutectic system above ~40 GPa. Here we performed melting experiments in a laser-heated diamond-anvil cell (DAC) and obtained the Fe-FeH eutectic melting cu…
