Figure 9
(a) XAS spectra of pure components used in the linear decomposition fit (shifted vertically for clarity). From bottom to top: blue, `cold b.c.c.' (at room temperature) α-Fe corresponding to the time-stamp 1 in Fig. 8[link]; pink, `hot b.c.c.' (∼1200 K) α-Fe (time-stamp 2 in Fig. 8[link]); black, γ-Fe (time-stamp 3 in Fig. 8[link]); red, Fe2O3 hematite (time-stamp 5 in Fig. 8[link]). (b) Temperature evolution of the α-Fe phase estimated from EXAFS fits. Zero on the timescale indicates the moment at which the laser is switched on.
