| Research Abstract |
Hydrogen is one of the most important candidates as light elements in the Earth's core. To understand the behavior of hydrogen in the Earth's core and its effect on the structure and dynamics of the core, experimental studies of crystal structures, phase relations, and their properties in iron-hydrogen (Fe-H) system are needed at high pressures and temperatures. In the Fe-H system we developed a high-pressure and high-temperature generation technique up to about 100 GPa and 2000 K using a laser-heated diamond anvil cell. The double hexagonal close-packed of iron hydride (FeH) was observed up to about 100 GPa, which suggests that FeH is possibly stable in the Earth's core.
