文摘
Fe3O4 (magnetite), α-Fe2O3 (hematite), and FeO (wüstite) are the three major iron oxides and some of the most fundamental solids in nature. Interest in these systems is due to their abundance as minerals in the Earth and other telluric planets as well as their interesting electronic and magnetic properties which have been studied for decades. In this article, we review high-pressure studies on these three systems using neutron powder diffraction in the 0-4?GPa range with a particular focus on the behavior of magnetism under pressure. Unpublished data on the pressure dependence of the Néel temperature in FeO are presented. This review will give at the same time an introduction into technical aspects and illustrate the potential of high-pressure neutron scattering in the future.
