Interpretation of the Mössbauer spectrum of fcc Au-Fe alloys

Literature data indicate that the Mössbauer spectrum of ${\mathrm{Au}}_{82}$ ${\mathrm{Fe}}_{18}$ and similar alloys has two six-line components, both originating in locally ferromagnetic regions. A magnetic structure is proposed, assuming that, alongside the two-atomic-layer Fe platelets found by x-ray diffuse scattering, there are present in these alloys three-layer Fe platelets as well.
