Site-specific spin crossover in Fe${}_2$TiO${}_4$ post-spinel under high pressures to near a megabar

W. M. Xu, G. R. Hearne, S. Layek +5

X-ray diffraction studies to ~90 GPa at room temperature show that Fe${}_2$TiO${}_4$ ferrous inverse spinel undergoes the following sequence of structural transitions : cubic (Fd3m…
