Abstract

Abstract Very thin Fe films epitaxially grown on Ag(100) have been studied by means of spin-resolved inverse photoemission spectroscopy. Results for film thicknesses in the range 1–100 bcc Fe monolayers are reported. It is shown that the exchange splitting δ E ex at the H point of the bcc Fe Brillouin zone reaches the bulk value of 1.8 eV for film thicknesses larger than 15 ML; for thinner films, the exchange splitting is reduced. Moreover, it is found that films thinner than 5 ML do not show any in-plane remanent magnetization.
