ABSTRACT
Recent years have seen a great development in the research on magnetic
thin films and multi-layers, due to potential technical applications in
magnetic devices such as magnetic memories and sensors. Various unusual
magnetic phenomena with no counterpart in bulk materials result from the
2-dimensional film geometry, as for example, magnetic size effects and
magnetic couplings in multi-layers. Spin- and angular-resolved photoemission
is well suited to investigate the magnetic properties of ultra-thin films.
Applications of this technique will be illustrated in relation to three
different aspects of the magnetism of Fe(110) ultra-thin films: i) the
spin-polarized electronic structure of the Fe(110) surface; ii) the reorientation
of the magnetization between the two in-plane high-symmetry directions
([001] vs. [110]); iii) the magnetic properties of the Fe-Oxide/Fe(110)
bilayer.
