Geodynamics Seminar
"Exploration of crystal structures of iron by free energy surface
trekking"
石河 孝洋(GRC教員)
主催 : 愛媛大学地球深部ダイナミクス研究センター
日時 : 2009年4月17日(金)※16:30〜
場所 : 愛媛大学総合研究棟T4F会議室
要 旨
Iron has been expected to take the hexagonal close-packed (hcp)
structure at Earth’s inner core conditions. However, the information
obtained by my previous research for calcium indicates that iron has a
possibility to take complex crystal structures at the core. In the
seminar, I will introduce my developing algorithm for the exploration of
the structures under high-pressure and high-temperature, Free Energy
Surface Trekking (FEST), and I will show the results obtained by
applying FEST to iron at 400GPa.
