Ni K fluorescence EXAFS spectra of a horizontal 20 µm-wide permalloy strip of the IRMM-301 reference standard recorded with polycapillary focusing, and the transmission spectrum on a Ni foil without focusing; k1χ(k) spectra (top) and FT[k3χ(k)] (bottom) (IRMM: Δk = 2.40–11.31 Å−1; Ni foil: Δk = 2.42–11.36 Å−1). The EXAFS spectra corrected for self-absorption (SA) are also added. |
