Pressure tuning of charge ordering in iron oxide

The charge order transition of commonly known magnetite has only recently been unraveled. Here, the measurement of the low-temperature high-pressure phase diagram of a related material (Fe4O5) elucidates the interplay of average oxidation state and charge-ordering phenomena in the iron oxide family.
