Epitaxial (110)56 Fe samples have been grown on (111) Ag and then covered with MnF2 in ultrahigh vacuum. Three 57 Fe layers have been placed at various depths from the Fe/MnF2 interface to permit Mössbauer spectroscopy. A linear temperature dependence of the hyperfine field for 57 Fe layers up to at least 10 layers into the sample is observed. This persistence of surface magnetic effects into the deep layers of the (110) Fe sample can be understood within the framework of a classical spin-wave calculation by Rado.
