Pressure tuning of charge ordering in iron oxide

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.
