Figure 1
(a) Assumed sample condition. (b, c) Calculated GIMS spectra for Δm = 0 transitions of the ferromagnetic iron thin films. The 57Fe isotope enrichment is (b) 95% and (c) 2.17%. In the graphs the horizontal axis is the energy of the incident beam. According to the custom in Mössbauer spectroscopy, the x-axis is shown as the velocity, whose zero corresponds to the centre of the sextet of α-Fe (lower horizontal axis). For the reader's convenience, this axis is also shown as the energy in units of the natural line width of the 57Fe nuclear resonance, Γ (upper horizontal axis). |
