Mössbauer reflectivity spectra at grazing-incidence angle θ = 3 mrad (slightly below the critical angle of the total external reflection), calculated for the [57Fe(0.8 nm)/Cr(1.05 nm)]30 multilayer characterized by the collinear antiferromagnetic alignment between 57Fe layers. The spectra are calculated assuming π-polarization of the incident radiation for the [{\bf{B}}_{\rm{hf}}^{1,2}] orientation in the surface plane ([\beta] = 90°) and various azimuth angles [\gamma]. The red curve, marked by the blue circles, shows the spectrum for the randomly distributed orientation of the antiferromagnetically coupled [{\bf{B}}_{\rm{hf}}^{1,2}] in the surface plane. For clarity, the subsequent spectra are shifted vertically.
