Abstract
The magnetic properties of fcc Fe thin films with a thickness of 1-11 monolayers (ML) grown at room temperature on fcc Co, which was prepared more than 15 ML on Cu(001), have been studied by spin-resolved core level and valence band photoelectron spectroscopy. The observed exchange split valence band structures show that Fe films below 11 ML are in a high spin ferromagnetic phase. Based on the line shape analysis of 3s core level spectra with a cluster model calculation and considering the probing depth of photoelectron spectroscopy, we demonstrate that in the 5-11 ML region, only the topmost few layers of Fe film reveal ferromagnetism as observed in the Fe/Cu(001) system.
