Stability and nature of the volume collapse of ε-Fe2O3 under extreme conditions

Iron oxides exist in a variety of polymorphs at different pressure and temperature conditions, displaying important magnetic properties, and are major constituents of the Earth’s interior. Here the authors investigate the structural and electronic changes in the uncommon epsilon phase under compress...

Sumario:Iron oxides exist in a variety of polymorphs at different pressure and temperature conditions, displaying important magnetic properties, and are major constituents of the Earth’s interior. Here the authors investigate the structural and electronic changes in the uncommon epsilon phase under compression to deep Mantle pressures.
