“…Since the electron mean free path in Fe deduced from the attenuation of the substrate Cu 60 eV Auger line is much smaller ͑Ͻ5 Å͒, we conclude that and ␥ phases coexist in the film for coverages above 5.5 Å, in agreement with Ref. 5.…”

“…We stress that all the films have been systematically deposited with the substrate held at 300 K. This has been done in order to be consistent with the experimental procedure of Ref. 5. In fact, it has been observed that a different substrate temperature during the growth leads to a different thickness dependence of the structure 8 and of the magnetism 2 of the films.…”

“…More recent investigations 5 revealed the presence of a complex scenario in which different structural phases of Fe were found to coexist for films deposited at RT. An almost undistorted face centered tetragonal ͑fct͒ structure was found for coverage Ϸ3 Å.…”

“…We focus our attention on the whole thickness range for which the coexistence of two fct phases was observed. 5 The upper thickness limit is set by the nucleation of the bct phase. We observe that the coexistence of fct structures affects the magnetic properties of the films; the thickness dependence of the Curie temperature T C clearly reflects the different magnetic properties of the two fct phases.…”

We have studied the correlation between the magnetic properties and the structure of ultrathin ferromagnetic Fe/ Cu 3 Au͑001͒ films for thicknesses up to 15 Å. We have found that two different face centered tetragonal structural phases coexist within the film in the thickness range 5-15 Å. The coexistence of the two structural phases induces an anomalous thickness dependence of the Curie temperature of the films. We ascribe this thickness dependence to a difference in the exchange coupling between the two phases. The irreversible modifications of the magnetic properties of the films after a mild thermal treatment are discussed on the basis of the corresponding changes of the structure and the morphology.
