Abstract
Iron layers of monolayer thick are synthesized between thick Au layers by alternate deposition of Fe and Au metals. From57Fe Mössbauer absorption spectroscopy, it is found that the Fe monolayer is ferromagnetic at 4.2 k. At higher temperatures, the spectra show a relaxation of the hyperfine field and above 150 K, all Fe atoms are observed as a doublet in the spectra.
