| Outline of Final Research Achievements |
We determined the melting relations of Fe-S, Fe-C, Fe-H, Fe-Ni and Fe-S-Si, Fe-S-H systems, and compression of hcp-FeNiSi and hcp-FeNiS alloys, Fe_3S, and Fe3C to the core conditions. We also successfully measured compressional velocity of hcp-iron to 173 GPa at 3000 K, which are the data determined at the highest pressure and temperature by the IXS method. We also determined the spin-state and magnetic properties of the iron-oxides and iron-light element compounds at high pressure. Based on these experimental results we proposed the model of the composition and the temperature profile of the core.
