Abstract
Thin iron films (∼18 Å and 90% enriched in Fe57) were prepared on (001) Cu single‐crystal substrates. The fcc structure was verified by electron microscopy. By Mössbauer spectroscopy it was found that antiferromagnetic ordering begins at around 80±10 K with hyperfine fields of about 16–20 kOe. Additional proof for the existence of anitferromagnetism has been obtained by measuring the films in a longitudinal (parallel to the γ‐ray direction) external magnetic field. The apparent discrepancy in the literature of ferromagnetic and antiferromagnetic ordering in fcc films might be resolved by taking into account the differences concerning the film orientations.This publication has 19 references indexed in Scilit:
