Figure 4
Calculated Mössbauer reflectivity spectra at the `magnetic' maximum (θ = 12.2 mrad) for the [57Fe(0.8 nm)/Cr(1.05 nm)]30 multilayer. The spectra are calculated for π-polarization of the incident radiation, and for various orientations of the hyperfine magnetic fields in the surface plane, shown by the pictograms near each spectrum. The spectra for the collinear antiferromagnetic coupling are on the left, and those for the noncollinear coupling are on the right panel. The spectra at the bottom of both panels correspond to the almost vanished intensity of the `magnetic' maximum. The curves are vertically shifted for clarity. |
