Figure 8
Normalized X-ray absorption near Fe K-edge as a function of time. Small black arrows indicate time of the following events: 1, heating laser turned on; 2, sample temperature reaches ∼1200 K and a phase transition from α-Fe to γ-Fe starts; 3, phase transition is finished, only a pure γ-Fe phase is observed; 4, first traces of iron oxide appear in spectra; 5, the oxidation is complete and the sample is fully converted to Fe₂O₃ hematite.
