(a) Iron phase diagram and isochoric path for the bcc, fcc and liquid phases. The dots indicate roughly estimated P, T conditions for the black, red, pink and blue spectra shown in (b). (b) Sequence of Fe K-edge XANES selected during a fast ohmic ramp. The bottom spectrum (black) has been collected before the start. Acquisition time is 25 µs per spectrum.
