| Resumo: | We have investigated the magnetic properties of monolayers of FCC Fe grown epitaxialy on Cu84A116(1 0 0) and on ordered Cu3Au(1 0 0), substrates that present lattice parameters 1 per centum and 3.7 per centum bigger than pure Cu. The magnetic measurements were carried out by linear magnetic dichroism in the angular distribution of photoelectrons (LMDAD), using linearly polarized synchrotron radiation. The LMDAD measurements of the Fe 3p core levels show that strating from 2.5 monolayers (ML) for Fe/Cu84A116(1 0 0) and from 4 ML for Fe/Cu3Au(1 0 0) these FCC Fe films present in-plane ferromagnetism. The 9 per centum inclrease of the magnetic splitting of the Fe 3p LMDAD peak-ti peak asymmetry measured for Fe/Cu3Au(1 0 0) suggests an increase of the Fe magnetic moment with increasing volume of the high-spin FCC Fe films. |
