      abstract     = {The microscopic structure of Fe-based metallic glasses
                      (FeGaB) and (FeCoSiB) is investigated during in situ thermal
                      annealing using extended X-ray absorption fine structure
                      spectroscopy (EXAFS) above the Fe–K and Co–K absorption
                      edges. FeGaB exhibits a phase transition above 450 °C,
                      changing from amorphous glass to a partially crystalline
                      structure. Its medium-range structure after this transition
                      is modeled from crystalline α-Fe and reference structures,
                      combined with amorphous nearest-neighbor (NN) contributions
                      of . Local order in the glass phase is described with the
                      same model, restricted to NN interactions. Changes in the
                      amorphous structure occur at annealing temperatures which
                      coincide with typical observations of changes in magnetic
                      behavior. Meanwhile, in FeCoSiB, the EXAFS response is
                      highly different between the Fe–K and Co–K absorption
                      edges. EXAFS oscillations on the Fe edge are strongly
                      suppressed, as opposed to the Co edge which shows typical
                      amplitudes. Limited resolution in this data set allows
                      modeling only in the first amorphous shell, based on the NN
                      distances from FeCo. The cause of the two materials’
                      different EXAFS behavior at Fe–K despite similar iron
                      content and identical experimental conditions is currently
                      unknown and subject of further investigation.},
