Abstract
By means of Magnetic Circular Dichroism in X-ray Absorption Sectroscopy we investigated the magnetic properties of fet Fe tilms stabilised by epitaxial growth on the Cu(100) surface. These are compared to bee like Fe films. The films were characterised in situ by means of LEED, AES and XAS for order and cleanness. Low temperature (≈ 50 K) and angle dependent measurements are reported for thickneses around 3.5 (fct (5 × 1) phase) and 20 (bee phase) monolayers. A much stronger MCD response is obtained from the thimner films (perpendicular magnetisation). The MCD sum rules enabled as to dertermiine the orbital and spin contributions to the magnetic moment for the two phases. The results are compared to theory.
